| Частное | \( 24 : 4 = 6 \) | \( 18 : 6 = 3 \) | \( 25 : 5 = 5 \) | \( 48 : 2 = 24 \) | \( 36 : 3 = 12 \) | \( 52 : 2 = 26 \) |
| Произведение | \( 24 \cdot 4 = 96 \) | \( 18 \cdot 6 = 108 \) | \( 25 \cdot 5 = 125 \) | \( 48 \cdot 2 = 96 \) | \( 36 \cdot 3 = 108 \) | \( 52 \cdot 2 = 104 \) |
\( 49 + 35 = 84 \)
\( 28 + 29 = 57 \)
\( 81 - 56 = 25 \)
\( 63 - 37 = 26 \)
\( 72 : 24 = 3 \)
\( 96 : 48 = 2 \)
\( 145 + 65 = 210 \)
\( 702 - 613 = 89 \)
\( 241 \cdot 4 = 964 \)
\( 840 : 4 = 210 \)
\( 1 \cdot (2 + 4 : 2) = 1 \cdot (2+2) = 1 \cdot 4 = 4 \)
\( 42 : 21 \cdot 60 - 31 = 2 \cdot 60 - 31 = 120 - 31 = 89 \) (Исходное равенство: \( 42 : 21 \cdot 60 - 31 = 38 \) неверно, поэтому скобки не помогают)
\( (22 + 35) - 31 \cdot 2 = 57 - 62 = -5 \) (неверно)
\( 22 + 35 - 31 \cdot 2 = 22 + 35 - 62 = 57 - 62 = -5 \) (неверно)
\( 44 : 34 + 10 + 2 = 3 \) (неверно)
\( 44 : (34 + 10) + 2 = 44 : 44 + 2 = 1 + 2 = 3 \)
