What went wrong
5 + 42 =13
21,
42 means 4x4 they did 4x2
Give the correct order of operations.
Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction
54 in expanded form
5 x 5 x 5 x 5
(14 + 6) x (12 -4) -9

if x=4
3x + 8 + 2x -6
What is 22
10÷5 x 2 = 1
They multiplied first, they should have divided since it came first.
10÷5 x 2 = 4
What is the saying we use to remember the correct Order of Operations?
Please Excuse My Dear Aunt Sally
5 x 5 x 6 x 6 x 6 in Exponent form
52 x 63
(15 - 5) x 10 + 3

In 2(42- 9/3 x 2) + 18 this is the first step
9/3
45 = 4 x5

45 means 4x4x4x4x4 not 4x5
This is a math problem with no = sign

When solving the equation 2x + x + 8 = 4x + 3 I first need to ask myself
What is: are the x's on only one side?
3 x 3 x 3 x 3 x 3 is 53
What is: the base and exponent are flipped.
left to right
50 ÷ (8-3)2 + 16 with proof
18
( 10 + 19 -5 ) x 2

This is the math problem used to find the area of a yard that is 30.5 feet wide and 20 feet long
What is 30.5 x 20
The problem was
20 - 5 x 2 + 3 = 33
They did not multiply first. (The subtracted first) The answer should be 13.
These are 3 ways to show division
What are: the division symbol, division box, fraction bar
7 + 32 x (8 ÷ 4)

Every number in 53 has a specific name
5 is the base, 3 is the exponent
