Решите примеры по действиям! 1) 25x(63-741:19) 2) (900-7218:9)x12 3)3926:13x8+2584 4)690-2944:64x15

Answer 1

 25 *(63 - 741:19) = 600
1) 741:19 = 39
2) 63 - 39 = 24
3) 25 * 24 = 600

(900 - 7 218:9)*12 = 1 176
1) 7 218 : 9 = 802
2) 900 - 802 = 98
3) 98 * 12 = 1 176

3 926:13*8 + 2 584 = 5 000
1) 3 926:13 = 302
2) 302 * 8 = 2 416
3) 2 416 + 2 584 = 5 000

690 - 2 944:64*15 = 0
1) 2 944:64 = 46
2) 46 *15 = 690
3) 690 - 690 = 0
