# DATA TYPES: Strings & Integers

name = "Sasha"
age = "12"

# 'name' is the String, 'age' is the Integer
#  the equal sign is extremely important!

num1 = 10
num2 = 15

num3 = num1 + num2

# what's the value of num3?
# answer: 25

## Integer Operations

a = 5
b = 8

a + b #returns 13; addition
a * b #returns 40;  multiplication
a - b #returns -3; subtraction
a / b #returns 0.625; division

## String Operations

first = "Sasha"
last = "Fierce"

beyonce = first + " " + last #returns: Sasha Fierce

## Invalid Operations

name + age #returns an error; can't mix Strings and Integers
