Question

(43-7):6+7*7;8*9-30:3+21;81:9+5*(18:2);(11-8)*9-26*1

Answer 1

(43 - 7) ÷ 6 + 7 × 7 = 36 ÷ 6 + 49 = 6 + 49 = 55

8 × 9 - 30 ÷ 3 + 21 = 72 - 10 + 21 = 62 + 21 = 83

81 ÷ 9 + 5 × (18 ÷ 2) = 9 + 5 × 9 = 9 + 45 = 54

(11 - 8) × 9 - 26 × 1 = 3 × 9 - 26 = 27 - 26 = 1

Answer 2

Let's solve each expression step by step:

1. (43 - 7):6 + 7 * 7 First, perform the subtraction inside the parentheses: 36:6 + 7 * 7 Then, perform the division: 6 + 7 * 7 Finally, perform the multiplication: 6 + 49 The result is 55.

2. 8 * 9 - 30:3 + 21 First, perform the division: 8 * 9 - 10 + 21 Then, perform the multiplication: 72 - 10 + 21 Finally, perform the subtraction and addition: 83 The result is 83.

3. 81:9 + 5 * (18:2) First, perform the division inside the parentheses: 81:9 + 5 * 9 Then, perform the multiplication: 9 + 5 * 9 Finally, perform the addition and multiplication: 54 The result is 54.

4. (11 - 8) * 9 - 26 * 1 First, perform the subtraction inside the parentheses: 3 * 9 - 26 * 1 Then, perform the multiplication: 27 - 26 * 1 Finally, perform the subtraction: 27 - 26 The result is 1.

So, the results of the expressions are:

1. (43-7):6+7*7 = 55
2. 8*9-30:3+21 = 83
3. 81:9+5*(18:2) = 54
4. (11-8)9-261 = 1
