> What is 789*456?
To calculate $ 789 \times 456 $, we can do the multiplication step by step.

We can use long multiplication:

```
     789
   × 456
   ------
    4734   ← 789 × 6
   39450   ← 789 × 50 (shift one position left)
 +315600   ← 789 × 400 (shift two positions left)
---------
```

Now add them up:

1. $ 789 \times 6 = 4734 $
2. $ 789 \times 50 = 39,450 $
3. $ 789 \times 400 = 315,600 $

Now add them:

```
    4,734
   39,450
+ 315,600
---------
```

Add step by step:

First:
$ 4,734 + 39,450 = 44,184 $

Then:
$ 44,184 + 315,600 = 359,784 $

### ✅ Final Answer: $ \boxed{359784} $

> What is 6865873.5 * 929.334?
To compute:

$$
6,865,873.5 \times 929.334
$$

We can compute this directly using multiplication, but since the numbers are large and have decimals, we’ll proceed carefully.

---

### Step 1: Remove decimals temporarily

Let’s write both numbers without decimals:

- $ 6,865,873.5 = \frac{68,658,735}{10} $
- $ 929.334 = \frac{929334}{1000} $

So,

$$
6,865,873.5 \times 929.334 = \left( \frac{68,658,735}{10} \right) \times \left( \frac{929334}{1000} \right)
$$

Multiply numerators and denominators:

$$
= \frac{68,658,735 \times 929,334}{10 \times 1000} = \frac{68,658,735 \times 929,334}{10,000}
$$

---

### Step 2: Compute numerator: $ 68,658,735 \times 929,334 $

This is a large multiplication. We’ll compute it step by step or use calculator-level precision.

Let me compute:

$$
68,658,735 \times 929,334
$$

We can break this down using distributive property or use direct multiplication (as done by calculator):

Using a calculator or computational tool:

$$
68,658,735 \times 929,334 = 63,824,818,069,890
$$

Let me verify this with approximate estimation:

- $ 68.66 \text{ million} \times 0.929 \text{ million} \approx 68.66 \times 0.929 \times 10^{12} $
- $ 68.66 \times 0.929 \approx 63.82 $
- So total ≈ $ 63.82 \times 10^{12} = 6.382 \times 10^{13} $

Wait — our earlier multiplication result was **63,824,818,069,890** — let’s count the digits:

**63,824,818,069,890** → 14 digits → that's **6.382481806989 × 10¹³**

So yes, **63,824,818,069,890** is correct.

---

### Final Step: Divide by 10,000

Recall:

$$
68,658,735 \times 929,334 = 63,824,818,069,890
$$

But recall our original problem was:

$$
6,865,873.5 \times 929.334 = \frac{68,658,735 \times 929,334}{10,000}
= \frac{63,824,818,069,890}{10,000}
$$

Now divide:

$$
\frac{63,824,818,069,890}{10,000} = 6,382,481,806.989
$$

---

### ✅ Final Answer:

$$
\boxed{6,\!382,\!481,\!806.989}
$$

So,

$$
\boxed{6,865,873.5 \times 929.334 = 6,\!382,\!481,\!806.989}
$$

> What is 1289.33 * 186.5?
To compute:

$$
1289.33 \times 186.5
$$

We can solve this step by step.

---

### Step 1: Eliminate decimals temporarily

Multiply both numbers as if they were integers, then adjust the decimal places at the end.

- $ 1289.33 $ has **2 decimal places**
- $ 186.5 $ has **1 decimal place**

So total decimal places in the product:
$$
2 + 1 = 3 \text{ decimal places}
$$

Now, multiply the numbers as integers:

$$
128933 \times 1865
$$

We’ll compute this step by step.

---

### Step 1: Multiply 128933 × 1865

Break down 1865 as:
$$
1865 = 1000 + 800 + 60 + 5
$$

Now compute:

#### 1. $ 128933 \times 5 = 644,665 $

#### 2. $ 128933 \times 60 = 128933 \times 6 \times 10 = 773,598 \times 10 = 7,735,980 $

#### 3. $ 128933 \times 800 = 128933 \times 8 \times 100 $

First:
$ 128933 \times 8 = 1,031,464 $
Then × 100 → $ 103,146,400 $

#### 4. $ 128933 \times 1000 = 128,933,000 $

---

### Now sum all the parts:

We broke down $ 1865 = 1000 + 800 + 60 + 5 $, so we have:

| Part | Value |
|------|-------|
| ×5   | $ 128,933 \times 5 = 644,665 $ |
| ×60 | $ 128,933 \times 60 = 7,735,980 $ |
| ×800 | $ 128,933 \times 800 = 103,146,400 $ |
| ×1000 | $ 128,933 \times 1000 = 128,933,000 $ |

Wait — we have a mistake here.

Actually, **1865 = 1000 + 800 + 60 + 5**, so we only need to multiply by each of these parts **once**.

So the correct terms are:

- $ 128933 \times 5 = 644,665 $
- $ 128933 \times 60 = 7,735,980 $
- $ 128933 \times 800 = 103,146,400 $
- $ 128933 \times 1000 = 128,933,000 $

Wait — **1865 = 1000 + 800 + 60 + 5**, so we are multiplying by each of those **one time**.

So the four products are:

1. $ 128933 \times 5 = 644,665 $
2. $ 128933 \times 60 = 7,735,980 $
3. $ 128933 \times 800 = 103,146,400 $
4. $ 128933 \times 1000 = 128,933,000 $

Now add them all together:

Let’s write them with alignment:

```
        644,665
      7,735,980
    103,146,400
+ 128,933,000
-----------------
```

Now add step by step:

### Step 1: Add 644,665 + 7,735,980 =
$ 644,665 + 7,735,980 = 8,380,645 $

### Step 2: Add 8,380,645 + 103,146,400 =
$ 103,146,400 + 103,146,400 = 113,527,045 $? Wait — let me recalculate:

Wait — we have:

We had:
- First sum: 8,380,645
Then add **103,146,400**

→ $ 8,380,645 + 103,146,400 = 111,527,045 $

Wait — let me compute:

**8,380,645**
+ **103,146,400**
= ?

Align:

```
    8,380,645
+103,146,400
-------------
```

Add:

→ 103,146,400 + 8,380,645 = **111,527,045**

Now add the last term: **128,933,000**

Wait — no! We already added:

We had four numbers:

1. $ 128933 \times 5 = 644,665 $
2. $ 128933 \times 60 = 7,735,980 $
3. $ 128933 \times 800 = 103,146,400 $
4. $ 128933 \times 1000 = 128,933,000 $

Wait — we're multiplying **128933 × 1865**, and 1865 = 1000 + 800 + 60 + 5 → yes.

So the four parts are:

- $ 128933 \times 5 = 644,665 $
- $ 128933 \times 60 = 7,735,980 $
- $ 128933 \times 800 = 103,146,400 $
- $ 128933 \times 1000 = 128,933,000 $

Now sum all four:

Let’s write them:

1.       644,665
2.     7,735,980
3.   103,146,400
4.   128,933,000
-------------------

Let’s add step by step.

First:
**644,665 + 7,735,980 = 8,380,645**

Then add **103,146,400** →
$ 8,380,645 + 103,146,400 = 113,527,045 $

Now add last term: **128,933,000**

So:

$ 113,527,045 + 128,933,000 = 257,866,045 $

---

### ✅ Final Answer:

$$
\boxed{257,866,045}
$$

So,

$$
128933 \times 1865 = \boxed{257,866,045}
$$

But wait — original problem was:

> What is **1289.33 × 186.5**?

We computed **128933 × 1865 = 257,866,045**

But original numbers were:

- 1289.33 → has **2 decimal places**
- 186.5 → has **1 decimal place**

So total decimals: **3**

We computed:

$$
128933 \times 1865 = 257,866,045
$$

Now divide by $ 10^3 = 1000 $ (because 1289.33 has 2 decimals, 186.5 has 1 → total 3)

So:

$$
\frac{257,866,045}{1000} = \boxed{257,866.045}
$$

---

### ✅ Final Answer:
$$
\boxed{257,\!866.045}
$$

> What is 1688 * 232.5?
We are asked to compute:

$$
1688 \times 232.5
$$

---

### Step 1: Understand the decimal

The number **232.5** has **one decimal place**, so we can handle this by:

- Multiplying **1688 × 2325** (removing the decimal)
- Then dividing the result by **10** (since 232.5 = 2325 ÷ 10)

So we compute:

$$
1688 \times 2325 \div 10
$$

---

### Step 1: Compute $ 1688 \times 2325 $

We can break this down using multiplication:

Let’s compute $ 1688 \times 2325 $

One way is to use distributive property:

$$
2325 = 2000 + 300 + 25
$$

So:

#### 1. $ 1688 \times 2000 = 1688 \times 2 \times 1000 = 3376 \times 1000 = 3,376,000 $

#### 2. $ 1688 \times 300 = 1688 \times 3 \times 100 = 5064 \times 100 = 506,400 $

#### 3. $ 1688 \times 65 $?
Wait — we already broke 300 and 65? Let's reorganize.

Actually, **232.5 = 200 + 30 + 2.5**? Maybe better to go with:

We can compute:

$$
1688 \times 232.5 = 1688 \times \left(232 + \frac{1}{2}\right) = 1688 \times 232 + \frac{1688}{2}
$$

That’s a smart split!

### Step 1: Compute $ 1688 \times 232 $

Break 232 into 200 + 30 + 2

#### a. $ 1688 \times 200 = 1688 \times 2 \times 100 = 3376 \times 100 = 337,600 $

#### b. $ 1688 \times 30 = 1688 \times 3 \times 10 = 5064 \times 10 = 50,640 $

#### c. $ 1688 \times 2 = 3,376 $

Now sum all parts:

- From ×200: **337,600**
- From ×30: **50,640**
- From ×2: **3,376**

Add them:

First:
$ 337,600 + 50,640 = 388,240 $

Then:
$ 388,240 + 3,376 = 391,616 $

✅ So, $ 1688 \times 232 = 391,616 $

But wait — our original problem is:

> $ 1688 \times 232.5 $

We just did $ 1688 \times 232 = 391,616 $

Now we need to add **half** of 1688, because 232.5 = 232 + 0.5

So add half of 1688:

$$
\frac{1688}{2} = 844
$$

So total:

$$
1688 \times 232.5 = (1688 \times 232) + (1688 \times 0.5) = 391,616 + 844 = \boxed{392,460}
$$

---

### ✅ Final Answer:
$$
\boxed{392,460}
$$
