Question

90•7-450:9=....... 160•4+13•3 502-237=..... 641-555=..... 274-186=...... 96-456=.......

Answer 1

90 * 7 - 450 : 9 =  580

90 * 7 = 630

450 : 9 = 50

630 - 50 = 580

...........................................

160 * 4 + 13 * 3 = 679

160 * 4 = 640

13 * 3 = 39

640 + 39 = 679

..............................................

502 - 237 = 265

...........................................

641 - 555 = 86

.............................................

274 - 186 = 88

...........................................

думаю, неправильно записано выражение.... ( так как ответ отрицательное число получается)

96 - 456 = - 360

Answer 2

Let's calculate the given expressions step by step:

1. 90 * 7 - 450 ÷ 9:

First, divide 450 by 9: 450 ÷ 9 = 50.

Then, multiply 90 by 7: 90 * 7 = 630.

Finally, subtract the result of the division from the multiplication: 630 - 50 = 580.

So, 90 * 7 - 450 ÷ 9 = 580.

2. 160 * 4 + 13 * 3:

First, multiply 160 by 4: 160 * 4 = 640.

Then, multiply 13 by 3: 13 * 3 = 39.

Finally, add the two results together: 640 + 39 = 679.

So, 160 * 4 + 13 * 3 = 679.

3. 502 - 237:

Subtract 237 from 502: 502 - 237 = 265.

So, 502 - 237 = 265.

4. 641 - 555:

Subtract 555 from 641: 641 - 555 = 86.

So, 641 - 555 = 86.

5. 274 - 186:

Subtract 186 from 274: 274 - 186 = 88.

So, 274 - 186 = 88.

6. 96 - 456:

Subtract 456 from 96: 96 - 456 = -360.

So, 96 - 456 = -360.

Therefore, the results of the given expressions are as follows:

90 * 7 - 450 ÷ 9 = 580 160 * 4 + 13 * 3 = 679 502 - 237 = 265 641 - 555 = 86 274 - 186 = 88 96 - 456 = -360
