Explicație pas cu pas:

(76 - 7 + 12 : 4) : 9 • (40 • 7 - 100 : 10) = (69 + 3) :9 • (280 - 10) = 72 : 9 • 270 = 19440 : 9 = 2160

(85 - 8 + 24 : 6): 9 x (50 x 6 - 90 : 10) = (77 + 4) : 9 • (300 - 10) = 81 : 9 • 290 = 9 • 290 = 2619

6 + 6 • (6 + 6 • 6 + 6) - (63 + 6 : 6) : 8 = 6 + 6 • (6 + 36 + 6) - (63 + 1) : 8 = 6 + 6 • 48 - 64 = 6 + 288 - 64 = 294 - 64 = 230

8 + 8 • (8 + 8 • 8 + 8) - (41 +8 : 8) : 6 = 8 + 8 • (8 + 64 + 8) - (41 + 1) : 6 = 8 + 8 • 80 - 42 : 6 = 8 + 640 - 7 = 648 - 7 = 641

(63 + 63 • 22 - 1443): (72 + 32 • 56 - 1858) = (63 + 1386 - 1443) : (72 + 1792 - 1858) = 6 : 6 = 1

(74 + 74 • 12 - 862): (81 + 46 • 67 - 3153) = (74 + 888 - 862) : (81 + 3082 - 3153) = 100 : 10 = 10

8 + 8 • (253 - 30 : 6 - 72 : 9) - 309 - 73 • 5 = 8 + 8 • (253 - 180 - 8) - 309 - 365 = 8 + 8 • 65 - 674 = 8 + 520 - 674 = - 146

4 + 4 • (312 - 42 : 6-49 : 7) - 408 - 42 • 6 = 4 + 4 • (312 - 7 - 7) - 408 - 7 = 4 + 4 • 298 - 401 = 4 + 1192 - 401 = 795

36 : 9 + 13 • (552 - 36 • 7) + 22 = 4 + 13 • (552 - 252) + 22 = 4 + 13 • 300 +22 = 3900 + 26 = 3926
