Odpowiedź:
A) 6 * 12 - 52 : 4 = 72 - 13 = 59
(25 +75): (53 - 48) = 100 : 5 = 20
53-3 *(43-19) :6 = 53 - 3 * 24 : 6 = 53 - 72 : 6 = 53 - 12 = 41
B) (125:25 +50) :11 = (5 + 50) : 11 = 55 : 11 = 5
(8*7-50) * 6 :4 = (56 - 50) * 6 : 4 = 6 * 6 : 4 = 36 : 4 = 9
98+2*(38 +31*2) = 98 + 2 * (38 + 62) = 98 + 2 * 100 = 98 + 200 = 298
C) 126-10 *2³ = 126 - 10 * 8 = 126 - 80 = 46
2500:10²-5² = 2500 : 100 - 25 = 25 - 25 = 0
2⁴*4: (71-39) = 16 * 4 : 32 = 64 ; 32 = 2
