Question

1000-264×3+16×7= 125×5-429÷3+418= 142×5+123÷3= 115×4+620÷5=

Answer 1

Ответ:

1) 320

2) 900

3) 751

4) 584

Пошаговое объяснение:

1)

264 * 3 = 792

16 * 7 = 112

1000 - 792 + 112 =  320

2)

125 * 5 = 625

429 / 3 = 143

625 - 143 + 418 = 900

3)

142*5 = 710

123 / 3 =  41

710 + 41 = 751

4)

115 * 4 = 460

620 / 5 = 124

460 + 124 = 584

Answer 2

Let's calculate each of these expressions step by step:

1. 1000 - 264 × 3 + 16 × 7 First, perform the multiplications and then the additions/subtractions. 264 × 3 = 792 16 × 7 = 112 Now, the expression becomes: 1000 - 792 + 112 Now, subtract 792 from 1000: 1000 - 792 = 208 Finally, add 112 to 208: 208 + 112 = 320

2. 125 × 5 - 429 ÷ 3 + 418 First, perform the division and then the multiplications/additions. 429 ÷ 3 = 143 Now, the expression becomes: 125 × 5 - 143 + 418 Now, multiply 125 by 5: 125 × 5 = 625 Now, subtract 143 from 625: 625 - 143 = 482 Finally, add 418 to 482: 482 + 418 = 900

3. 142 × 5 + 123 ÷ 3 First, perform the division and then the multiplication/addition. 123 ÷ 3 = 41 Now, the expression becomes: 142 × 5 + 41 Now, multiply 142 by 5: 142 × 5 = 710 Finally, add 41 to 710: 710 + 41 = 751

4. 115 × 4 + 620 ÷ 5 First, perform the division and then the multiplication/addition. 620 ÷ 5 = 124 Now, the expression becomes: 115 × 4 + 124 Now, multiply 115 by 4: 115 × 4 = 460 Finally, add 124 to 460: 460 + 124 = 584

So, the results of these expressions are as follows:

1. 1000 - 264 × 3 + 16 × 7 = 320
2. 125 × 5 - 429 ÷ 3 + 418 = 900
3. 142 × 5 + 123 ÷ 3 = 751
4. 115 × 4 + 620 ÷ 5 = 584
