Worksheet 2 of 30 (6% complete)

Question 1

Simplify: (15 ÷ 14) + (10 + 9) ÷ 11
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 2.80
bodmas, complex

Question 2

Given @ means +, # means -, % means ÷, $ means ×, which symbols should be interchanged to make 12 # 14 @ 10 $ 10 = 44?
The equation is already correct or no single interchange works
interchange, complex

Question 3

If % means ÷, $ means ×, @ means +, # means -, then find the value of 2 # 10 $ 18
Substitute symbols: 2 - 10 × 18 = -178
substitution, basic

Question 4

A value decreases by 34% and then increases by 28%. What is the net percentage change?
Step 1: decrease by 34% → multiply by 0.6599999999999999
Step 2: increase by 28% → multiply by 1.28
Net change = -15.5%
percentage, reasoning

Question 5

Simplify: (6 + 4) + (11 + 10) × 10
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 220
bodmas, complex

Question 6

If @ means +, # means ×, $ means -, find 3 @ (12 # 10) $ 4
Step 1: (12 × 10) = 120
Step 2: 3 + 120 - 4 = 119
bodmas, brackets

Question 7

Given: S > P, R > Q, P < R. Which of the following is definitely true?
From S > P and R > Q, we can deduce Cannot determine
inequality, logic

Question 8

Given # means -, @ means +, % means ÷, $ means ×, which symbols should be interchanged to make 4 $ 4 @ 13 # 12 = 68?
The equation is already correct or no single interchange works
interchange, complex

Question 9

Simplify: (3/3 + 5/11) - 7/2
Following BODMAS, calculate step by step to get -45/22
fractions, bodmas

Question 10

If $ means ×, @ means +, % means ÷, # means -, then find the value of 13 % 8 $ 3
Substitute symbols: 13 ÷ 8 × 3 = 4.86
substitution, basic

Question 11

Simplify: (5/7 - 10/8) ÷ 5/4
Following BODMAS, calculate step by step to get -3/7
fractions, bodmas

Question 12

Find the missing number in the sequence: ?, 6, 12, 24
The pattern: Each term is multiplied by 2. Therefore, the missing number is 3
pattern, sequence

Question 13

If $ means ×, # means -, @ means +, % means ÷, then find the value of 18 @ 16 $ 15
Substitute symbols: 18 + 16 × 15 = 258
substitution, basic

Question 14

Find the missing number in the sequence: 8, 24, 72, ?, 648
The pattern: Each term is multiplied by 3. Therefore, the missing number is 216
pattern, sequence

Question 15

Which two numbers should be interchanged to make the equation 5 × 3 + 3 = 27 correct?
balance, interchange

Question 16

If @ means +, $ means -, # means ×, find 9 @ (7 # 3) $ 9
Step 1: (7 × 3) = 21
Step 2: 9 + 21 - 9 = 21
bodmas, brackets

Question 17

If % means ÷, # means -, $ means ×, @ means +, then find the value of 4 @ 6 % 2
Substitute symbols: 4 + 6 ÷ 2 = 7
substitution, basic

Question 18

Simplify: 2 ÷ (2 + (10 ÷ 10) × 9)
Apply BODMAS: brackets first, then multiplication/division, then addition/subtraction to get 3
bodmas, complex

Question 19

Given $ means ×, # means -, @ means +, % means ÷, which symbols should be interchanged to make 12 $ 3 % 13 @ 10 = 63?
The equation is already correct or no single interchange works
interchange, complex

Question 20

A value decreases by 29% and then increases by 22%. What is the net percentage change?
Step 1: decrease by 29% → multiply by 0.71
Step 2: increase by 22% → multiply by 1.22
Net change = -13.4%
percentage, reasoning
