This document focuses on the order of operations for evaluating expressions with whole numbers without exponents or grouping symbols. It provides a series of examples and rules for correctly performing calculations including addition, subtraction, multiplication, and division. Key steps include using grouping symbols first, followed by multiplication and division from left to right, and finally addition and subtraction.

1. Module 7: Working with
order of operations
Performing Two or More Operations
on Whole Numbers without
Exponents and Grouping Symbols

2. Evaluate the following expressions. Write your answers on your
answer sheet.
1) 15 + 3 – 6 =
2) 8 + 8 ÷ 2=
3) 75 ÷ 5 + 9 =
4) 20 – 4 + 6 x 3 =
5) 6 ÷ 3 + 10 × 3 =

4. RULES:
1. Perform all the operations inside the grouping symbols (parentheses
and brackets), and all operations below or above the division bar
2. Evaluate those with exponents first.
3. Perform multiplication and division as they occur from left to right.
4. Perform addition and subtraction as they occur from left to right.
(4 x 10) + 102
÷ 5.

5. (4 x 10) + 102
÷ 5.

8. First, perform operations within each
grouping symbols.
Next, evaluate exponential expressions.
Then, perform multiplication or division from left to
right or whichever operation comes first.
Finally, perform addition or subtraction from left to
right or whichever operation comes first.
(4 x 10) + 102
÷ 5.

9. 84 ÷ 6 x 22
– (9 + 7)

10. 20 + 5 x (15 - 8)

11. 8 x 33 + 63 ÷ 9 – 6

12. Solve the following equation
72 ÷ 2 x 4 – 25
+ 5
[48 – (3 x 5)] + (12 ÷ 3)
4 x 6 + (32
– 3)
