BODMAS Practice

What are the other ways we can say BODMAS?

(Choose two)

• BIDMAS

• PEMDAS

• BIFIDUS

• MASBOD

Answer explanation

BODMAS = Brackets, Order (Power of), Division, Multiplication, Addition, Subtraction

BIDMAS = Brackets, Indices, Division, Multiplication, Addition, Subtraction

PEMDAS (US) = Parentheses, Exponent, Multiplication, Division, Addition, Subtraction

Order = Indices = Exponent (rasing a number to the power of another number)

Using the BODMAS rule, calculate: (3 + 6) × (8 - 5)

• 46 

• 67 

• 42

• 27

Use BODMAS to calculate the following:

9(3+3)

• 18
• 36
• 54
• 27

Put brackets in the following to make the answers correct: 15 + 9 ÷ 6 - 4 = 0.

• 15 + (9 ÷ 6) - 4 = 0

• (15 + 9) ÷ 6 - 4 = 0

• 15 + 9 ÷ (6 - 4) = 0 

Answer explanation

Option A

15 + (9 ÷ 6) - 4 = ?

15 + 3 - 4 = ?

18 - 4 = 14

Answer B

(15 + 9) ÷ 6 - 4 = ? 

24 ÷ 6 - 4 = ?

4 - 4 = 0

Option C

15 + 9 ÷ (6 - 4) = ?

15 + 9 ÷ 2 = ?

15 + 4.5 = 19.5

Using the BODMAS rule, calculate: 6 × 7 - 4 × 8.

• 10
• 304

• 144

• 17

Answer explanation

6 × 7 - 4 × 8 = ?

42 - 32 = 10

Is the following statement true or false:
division and multiplication rank equally (going left to right) when solving calculations.

• true
• false

Answer explanation

Yes this is true. Refer to question one of this quiz.

BODMAS = PEMDAS (US)

Using the BODMAS rule, calculate: 7 + 6 (12 - 7)

• 65

• 72

• 37

• 149

Answer explanation

7 + 6 (12 - 7) - ?

7 + 6(5) = ?

7 + 6 x 5 = ?

7 + 30 = 37

When we see a number next to brackets, this is the same as multiplying the numbers.

Put brackets in the following to make the answers correct: 24 - 17 × 8 - 16 = 40.

• (24 - 17) × 8 - 16 = 40

• 24 - (17 × 8) - 16 = 40

• 24 - 17 × (8 - 16) = 40

Answer explanation

Answer A

(24 - 17) × 8 - 16 = ?

7 x 8 - 16 = ?

56 - 16 = 40

Option B

24 - (17 × 8) - 16 = ?

24 - 136 - 16 = ?

-112 - 16 = -128

Option C

24 - 17 × (8 - 16) = ?

24 - 17 x -8 = ?

24 + 136 = 160

Using the BODMAS rule, calculate: (7²+ 11) ÷ 5

• 5

• 3.7

• 12

• 51

Answer explanation

(7²+ 11) ÷ 5 = ?

(49 + 11) ÷ 5 = ?

60 ÷ 5 = 12
