Answer - 3
In order to do this equation you would follow PEMDAS. Being as there isn’t any parentheses, multiplication, or division involved, we only need step E ( exponents) and step S ( subtraction). In the acronym, E comes before S so we multiple 4 * 4 ( if you did not know: the exponent of 2 means you would multiply the number with itself.) 4 * 4 equals 16. The equation is now 16- 13. When you subtract the two, the product is 3.
