Вставьте такое пропущенное число, чтобы равенство оказалось верным.

Для решения этих примеров нужно сначала вычислить значение правой части выражения, а затем найти пропущенное число. 1) _ + 2 = 3 + 4 -> _ + 2 = 7 -> 5 + 2 = 7 2) _ + 9 = 9 + 6 -> _ + 9 = 15 -> 6 + 9 = 15 3) _ - 5 = 14 - 9 -> _ - 5 = 5 -> 10 - 5 = 5 4) 6 - 5 = 2 - _ -> 1 = 2 - _ -> 1 = 2 - 1 5) 2 + 9 = 14 - _ -> 11 = 14 - _ -> 11 = 14 - 3 6) 4 + 6 = 17 - _ -> 10 = 17 - _ -> 10 = 17 - 7 7) 11 - _ = 1 + 4 -> 11 - _ = 5 -> 11 - 6 = 5 8) 14 - _ = 10 + 3 -> 14 - _ = 13 -> 14 - 1 = 13 9) 8 - _ = 6 - 5 -> 8 - _ = 1 -> 8 - 7 = 1 10) 13 - _ = 12 - 8 -> 13 - _ = 4 -> 13 - 9 = 4 11) 16 - 8 = _ + 3 -> 8 = _ + 3 -> 8 = 5 + 3 12) 18 - 7 = _ + 9 -> 11 = _ + 9 -> 11 = 2 + 9 13) 8 + 1 = 15 - _ -> 9 = 15 - _ -> 9 = 15 - 6 14) 9 + 8 = 18 - _ -> 17 = 18 - _ -> 17 = 18 - 1 15) 1 + 8 = 5 + _ -> 9 = 5 + _ -> 9 = 5 + 4 16) 7 + 7 = 11 + _ -> 14 = 11 + _ -> 14 = 11 + 3 17) _ + 2 = 0 + 5 -> _ + 2 = 5 -> 3 + 2 = 5 18) _ + 7 = 13 + 2 -> _ + 7 = 15 -> 8 + 7 = 15 19) _ - 2 = 1 + 6 -> _ - 2 = 7 -> 9 - 2 = 7 20) 19 - 4 = _ + 8 -> 15 = _ + 8 -> 15 = 7 + 8 21) 3 - 1 = _ - 6 -> 2 = _ - 6 -> 2 = 8 - 6 22) 7 - 4 = _ - 7 -> 3 = _ - 7 -> 3 = 10 - 7 23) 1 + _ = 11 - 8 -> 1 + _ = 3 -> 1 + 2 = 3 24) 6 + _ = 12 - 2 -> 6 + _ = 10 -> 6 + 4 = 10 25) 5 + _ = 8 - 1 -> 5 + _ = 7 -> 5 + 2 = 7
