Answer 1

38 + 724 - (94 : 47 * 353 : 706) * 751 - 9 + 49 = 762 - 751 + 40 = 51
750:6×4×2-570+5-49×9 + 31 = 1000 - 570 + 5 - 441 + 31 = 1036 - 1011 = 25
276:3+846+153:9-33-18×51-4 = 92 + 846 + 17 - 33 - 918 = 955 - 951 = 4
2×32×(666-288+96-6-453):192+99 = (762 - 747)/3 + 99 = 104
124+516:258×(965-962) -2×434:7+27 = 124 - 6 - 124 + 27 = 21

Answer 2

Let's solve each of the mathematical expressions step by step:

1. 38 + 724 - 94 ÷ 47 × 353 ÷ 706 × 751 - 9 + 49

Step 1: Solve division and multiplication from left to right. 38 + 724 - 2 × 353 ÷ 706 × 751 - 9 + 49 38 + 724 - 2 × 0.5 × 751 - 9 + 49 38 + 724 - 751 - 9 + 49

Step 2: Solve addition and subtraction from left to right. 762 - 751 - 9 + 49 11 - 9 + 49 2 + 49 51

So, the result of the expression is 51.

2. 750 ÷ 6 × 4 × 2 - 570 + 5 - 49 × 9

Step 1: Solve division and multiplication from left to right. 750 ÷ 6 × 4 × 2 - 570 + 5 - 49 × 9 125 × 4 × 2 - 570 + 5 - 49 × 9 500 × 2 - 570 + 5 - 49 × 9 1000 - 570 + 5 - 49 × 9

Step 2: Solve multiplication. 1000 - 570 + 5 - 441

Step 3: Solve addition and subtraction from left to right. 430 + 5 - 441 435 - 441 -6

So, the result of the expression is -6.

3. 276 ÷ 3 + 846 + 153 ÷ 9 - 33 - 18 × 51 - 4

Step 1: Solve division and multiplication from left to right. 276 ÷ 3 + 846 + 153 ÷ 9 - 33 - 18 × 51 - 4 92 + 846 + 17 - 33 - 18 × 51 - 4 92 + 846 + 17 - 33 - 918 - 4

Step 2: Solve addition and subtraction from left to right. 938 + 17 - 33 - 918 - 4 955 - 33 - 918 - 4 922 - 918 - 4 4

So, the result of the expression is 4.

4. 2 × 32 × (666 - 288 + 96 - 6 - 453) ÷ 192 + 99

Step 1: Simplify the expression within the parentheses first. 2 × 32 × (666 - 288 + 96 - 6 - 453) ÷ 192 + 99 2 × 32 × (15) ÷ 192 + 99

Step 2: Solve the multiplication within the parentheses. 2 × 32 × 15 ÷ 192 + 99 960 ÷ 192 + 99

Step 3: Solve division and addition from left to right. 5 + 99 104

So, the result of the expression is 104.

5. 124 + 516 ÷ 258 × (965 - 962) - 2 × 434 ÷ 7 + 27

Step 1: Simplify the expression within the parentheses first. 124 + 516 ÷ 258 × (965 - 962) - 2 × 434 ÷ 7 + 27 124 + 516 ÷ 258 × 3 - 2 × 434 ÷ 7 + 27

Step 2: Solve the division and multiplication from left to right. 124 + 2 × 3 - 2 × 434 ÷ 7 + 27 124 + 6 - 2 × 434 ÷ 7 + 27 124 + 6 - 62 + 27

Step 3: Solve addition and subtraction from left to right. 130 - 62 + 27 68 + 27 95

So, the result of the expression is 95.
