Определи порядок действий и вычисли. (13*7+9) * 17 = 80-42:3+4*4 = 12*6:9+98:4 = 84:6*7+2 = 100 - (17*5-13*3) = (15*2-84:7) * 4=

1) (13 * 7 + 9) * 17 = (91 + 9) * 17 = 100 * 17 = 1700;

2) 80 - 42 : 3 + 4 * 4 = 80 - 14 + 4 * 4 = 80 - 14 + 16 = 66 + 16 = 82;

3) 12 * 6 : 9 + 98 : 4 = 72 : 9 + 98 : 4 = 8 + 98 : 4 = 8 + 49/2 = 32 1/2;

4) 84 : 6 * 7 + 2 = 14 * 7 + 2 = 98 + 2 = 100;

5) 100 - (17 * 5 - 13 * 3) = 100 - (85 - 13 * 3) = 100 - (85 - 39) = 100 - 46 = 54;

6) (15 * 2 - 84 : 7) * 4 = (30 - 84 : 7) * 4 = (30 - 12) * 4 = 18 * 4 = 72.
