поставь знаки арифметических действий: 27...3...7=17; 27...3...7=16;27...3...7=23..;27...3...=6;5...5...5..5=25;(5...5...5)...5=100; (5...5)...5...5=50; (5...5)... (5...5)=0;

27 - 3 - 7 = 20 - 3 = 17

27 : 3 + 7 = 9 + 7 = 16

27 + 3 - 7 = 30 - 7 = 23

27 - 3 · 7 = 27 - 21 = 6

5 · 5 + 5 - 5 = 25 + 5 - 5 = 25

(5 · 5 - 5) · 5 = (25 - 5) · 5 = 20 · 5 = 100

(5 · 5) + 5 · 5 = 25 + 25 = 50

(5 + 5) - (5 + 5) = 10 - 10 = 0
