Punctul a)
225 - 5 ÷ 5 × 4 × 25 =
= 225 - 1 × 4 × 25
= 225 - 4 × 25
= 225 - 100
= 125
Punctul b)
321 - (200 - 1 × 86) + (10 × 28 ÷ 7) =
= 321 - (200 - 86) + (280 ÷ 7)
= 321 - 114 + 40
= 207 + 40
= 247
Punctul c)
124 + 32 ÷ 8 × 115 - 81 ÷ 9 ÷ 3 × 100 =
= 124 + 4 × 115 - 9 ÷ 3 × 100
= 124 + 460 - 3 × 100
= 584 - 300
