Zadanie 1
a) 98 - 42 + 7 = 56 + 7 = 63
b) 71 - 26 - 6 = 45 - 6 = 39
c) 54 : 9 * 3 = 6 * 3 = 18
d) 63 : 9 + 73 = 7 + 73 = 80
e) 42 - 2 * 5 = 42 - 10 = 32
f) 34 + 6 * 5 = 34 + 30 = 64
Zadanie 2
a) 7 * 8 - 3 * 5 = 56 - 15 = 41
b) 8 * (4 + 5) = 8 * 9 = 72
c) 7 * 10 + 18 : 3 = 70 + 6 = 76
d) 60 - 4 * (8 - 5) = 60 - 4 * 3 = 60 - 12 = 48
e) 4 * (7 + 5) - 15 : 3 = 4 * 12 - 5 = 48 - 5 = 43
Zadanie 3
a) 7² + 7 * 2 = 49 + 14 = 63
b) 8² + 3 * 2³ = 64 + 3 * 8 = 64 + 24 = 88
c) (4 + 1)² + 5 * 8 = 5² + 40 = 25 + 40 = 65
d) 3 * (5² + 2³) = 3 * (25 + 8) = 3 * 33 = 99
