Question

40-5•3=? 24:6+7=? 16:2+4•4=? (11-2)•3=? 28:(12-5)=? 3•(14-8):9=?

Answer 1

$40 - 5 \times 3 = 40 - 15 = 25 \\ 24 \div 4 + 7 = 4 + 7 = 11 \\ 16 \div 2 + 4 \times 4 = 8 + 16 = 24 \\ (11 - 2) \times 3 = 9 \times 3 = 27 \\ 28 \div (12 - 5) = 28 \div 7 = 4 \\ 3 \times (14 - 8) \div 9 = 3 \times 6 \div 9 = 18 \div 9 = 2$

Answer 2

1)40-5•3=40-(15)=25

2)24:6+7=4+7=11

3)(11-2)•3=27

4)28:(12-5)=4

5)3•(14-8):9=2

Answer 3

Let's calculate each expression step by step:

1. 40 - 5 × 3 = 40 - 15 = 25

2. 24 ÷ 6 + 7 = 4 + 7 = 11

3. 16 ÷ 2 + 4 × 4 = 8 + 16 = 24

4. (11 - 2) × 3 = 9 × 3 = 27

5. 28 ÷ (12 - 5) = 28 ÷ 7 = 4

6. 3 × (14 - 8) ÷ 9 = 3 × 6 ÷ 9 = 2

So, the calculations are as follows:

1. 40 - 5 × 3 = 25
2. 24 ÷ 6 + 7 = 11
3. 16 ÷ 2 + 4 × 4 = 24
4. (11 - 2) × 3 = 27
5. 28 ÷ (12 - 5) = 4
6. 3 × (14 - 8) ÷ 9 = 2
