2-2х2+2:2=0 9:9+9-9x9=1 9:9+9-9x9=9 поставить скобки ипорядок действий
(2 - 2) * (2 + 2) / 2 = 0 1) 2 - 2 = 0 2) 2 + 2 = 4 3) 0 * 4 = 0 4) 0 / 2 = 0 ======= 9/9 + (9 - 9) *9 = 1 1) 9 - 9 = 0 2) 0 * 9 = 0 3) 9/9 = 1 ====== 9/(9 + 9 - 9)*9 = 9 1) 9 +9 = 18 2) 18 - 9 = 9 3) 9 / 9 = 1 4) 1 * 9 = 9
9:9+(9-9)х9=9 1)9-9=0 2)9:9=1 3)1+0=1 4)1х9=9
