Math Chimp worksheet on order of operations with equations to solve.

Let's solve each of the problems using the order of operations, often remembered by the acronym PEMDAS:

- Parentheses
- Exponents
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)

Problem 1: (12 - 6) × 10 - 4

1. Parentheses:
$ 12 - 6 = 6 $

Now the expression is:
$ 6 × 10 - 4 $

2. Multiplication:
$ 6 × 10 = 60 $

Now:
$ 60 - 4 $

3. Subtraction:
$ 60 - 4 = 56 $

✔ Answer: 56

Problem 2: 3 × 11 + (6 - 10)

1. Parentheses:
$ 6 - 10 = -4 $

Now:
$ 3 × 11 + (-4) $

2. Multiplication:
$ 3 × 11 = 33 $

Now:
$ 33 + (-4) = 33 - 4 $

3. Addition/Subtraction:
$ 33 - 4 = 29 $

✔ Answer: 29

Problem 6: (12 + 9) × 10 + 13

1. Parentheses:
$ 12 + 9 = 21 $

Now:
$ 21 × 10 + 13 $

2. Multiplication:
$ 21 × 10 = 210 $

Now:
$ 210 + 13 $

3. Addition:
$ 210 + 13 = 223 $

✔ Answer: 223

Problem 7: 7 × 5 + (2 - 5)

1. Parentheses:
$ 2 - 5 = -3 $

Now:
$ 7 × 5 + (-3) $

2. Multiplication:
$ 7 × 5 = 35 $

Now:
$ 35 + (-3) = 35 - 3 $

3. Addition/Subtraction:
$ 35 - 3 = 32 $

✔ Answer: 32
