    The document explains the order of operations, or BODMAS, for evaluating mathematical expressions. It provides examples of expressions with multiple operations and variables to calculate. It instructs the reader to first evaluate expressions within parentheses, then exponents, then multiplication/division from left to right, and finally addition/subtraction from left to right. A series of expressions are given for the reader to evaluate step-by-step using this order of operations.

    BODMAS

    I can solve expressions using the order of operations.

    Here are some multi-part expressions. Complete the underlined part of the expression first then
    use the answer to that to complete the expression.

    Here is an example: 3 × (2 + 6)
    3× 8 = 24

    1. 7 × (8 − 3) 6. 21 ÷ (4 + 3) 11. 9 × (3 + 3)

    2. 7 + 9 × 2 7. 10 - 9 ÷ 3 12. 23 - (3 + 1)

    3. 10 ÷ (6 – 4) 8. 7 + 6 × 4 13. (10 + 5) ÷ 5

    4. 12 ÷ (7 - 4) 9. (12 + 20) ÷ 4 14. 12 ÷ (7 - 4)

    5. (8 + 9) + 62 10. (13 - 6) × 5 15. (11 - 3) × 7

    Decide which part of each expression to calculate first, underline and complete as above.

    1. (12 – 7) × 8 2. 9 + 2 × 7 3. 18 ÷ (8 – 2)
    BODMAS
    I can solve expressions using the order of operations.

    1. (12 + 8) ÷ 4 = 6. (21 – 9) × 2 = 11. (8 + 13) ÷ 7 =

    2. (52 + 10) ÷ 5 = 7. 8 × 3 + 6 = 12. 25 - 11 × 2 =

    3. (8 + 9) + 62 = 8. 3 × (15 – 9) = 13. (72 + 11) ÷ 5 =

    4. 4 × 6 – 14 = 9. 63 - (35 + 12) = 14. 9 ÷ (10 – 7) =

    5. 18 ÷ (4 + 5) = 10. (14 + 21) ÷ 5 = 15. 26 – 3 × 7 =

    Complete these calculations by filling in the missing number.

    1. 4 × – 25 = 23 4. (5 + 9) ÷ =2 7. ÷ (7 – 2) = 3

    2. (26 - 10) ÷ =4 5. 9 × (12 – ) = 63 8. 8 2 + (66 - ) = 86

    3. 60 = 5 × (3 + ) 6. 45 = (5 + )×5 9. 6 = ÷ (11 – 4)
    BODMAS
    I can solve expressions using the order of operations.

    Calculate:
    1. (3 + 6) × (8 – 5) = 6. 8 ÷ (7 – 5) × 6 =

    2. 7 + 8 × 9 – 4 = 7. 9 × 3 + 18 ÷ 9 =

    3. 8 × (6 + 3) + 5 = 8. (124 ÷ 2) × 22 =

    4. (19 – 7) + 82 + 9 = 9. 23 – 3 × (5 + 8) =

    5. 9 × (5 + 6) + 4 = 10. 8 + 7 × (12 – 5) =

    Put brackets in the following to make the answers correct.


    1. 6 × 7 – 4 × 8 = 10 6. 8 × 7 – 4 ÷ 6 = 4

    2. 8 × 9 – 5 – 6 = 26 7. 9 + 23 – 5 × 5 = 7

    3. 24 – 17 × 8 – 16 = 40 8. 5 + 11 ÷ 7 – 3 = 4

    4. 14 + 6 × 4 – 32 = 6 9. 7 + 6 × 12 – 7 = 37

    5. 9 × 7 – 6 × 3 = 27 10. 15 + 9 ÷ 6 – 4 = 0

    Use all the following numbers to create an expression using order of operations: 3, 4, 6, 12
