Worksheet 7 of 30 (23% complete)

Question 1

Which two numbers should be interchanged to make the equation 2 + 8 - 12 = 50 correct?
balance, interchange

Question 2

Simplify: 6 × (4 ÷ 4) ÷ 10 - 5
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get -4.40
bodmas, complex

Question 3

If $ means -, # means ×, @ means +, find 5 @ (2 # 5) $ 6
Step 1: (2 × 5) = 10
Step 2: 5 + 10 - 6 = 9
bodmas, brackets

Question 4

Which two numbers should be interchanged to make the equation 7 - 8 - 8 = 44 correct?
balance, interchange

Question 5

If % means ÷, # means -, @ means +, $ means ×, then find the value of 16 % 3 @ 4
Substitute symbols: 16 ÷ 3 + 4 = 9.33
substitution, basic

Question 6

Given # means -, $ means ×, @ means +, % means ÷, which symbols should be interchanged to make 9 % 13 $ 4 @ 14 = 24?
The equation is already correct or no single interchange works
interchange, complex

Question 7

Find the missing number in the sequence: ?, 14, 19, 24
The pattern: Each term increases by 5. Therefore, the missing number is 9
pattern, sequence

Question 8

If @ means +, $ means ×, # means -, % means ÷, then find the value of 16 @ 19 % 19
Substitute symbols: 16 + 19 ÷ 19 = 17
substitution, basic

Question 9

Given: P > S, P < S, S > Q. Which of the following is definitely true?
From P > S and P < S, we can deduce R < Q
inequality, logic

Question 10

Given: R < S, S < P, S > P. Which of the following is definitely true?
From R < S and S < P, we can deduce R < Q
inequality, logic

Question 11

Find the missing number in the sequence: 8, 16, 32, ?, 128
The pattern: Each term is multiplied by 2. Therefore, the missing number is 64
pattern, sequence

Question 12

If $ means -, # means ×, @ means +, find 11 @ (4 # 10) $ 11
Step 1: (4 × 10) = 40
Step 2: 11 + 40 - 11 = 40
bodmas, brackets

Question 13

If # means -, $ means ×, % means ÷, @ means +, then find the value of 7 $ 6 # 12
Substitute symbols: 7 × 6 - 12 = 30
substitution, basic

Question 14

Simplify: 2/3 - (4/2 ÷ 6/6)
Following BODMAS, calculate step by step to get -4/3
fractions, bodmas

Question 15

If $ means ×, @ means +, # means -, % means ÷, then find the value of 15 % 18 $ 3
Substitute symbols: 15 ÷ 18 × 3 = 2.4899999999999998
substitution, basic

Question 16

Simplify: (9 ÷ 6) + (12 ÷ 7) - 3
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 0.21
bodmas, complex

Question 17

Find the missing number in the sequence: 3, ?, 81, 6561, 43046721
The pattern: Each term is multiplied by 3. Therefore, the missing number is 9
pattern, sequence

Question 18

If % means ÷, # means -, @ means +, $ means ×, then find the value of (8 @ 10) $ 7 % 5
Step 1: (8 + 10) = 18
Step 2: 18 × 7 ÷ 5 = 25.2
substitution, brackets

Question 19

Which two numbers should be interchanged to make the equation 10 - 8 × 12 = 37 correct?
balance, interchange

Question 20

Simplify: 15 ÷ (7 ÷ 3) + 9 + 9
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 24.43
bodmas, complex
