6. 4·2+4 8·3 18 – (15 – 7) 6·3:2 6·2+6 7·3 40 + (9+13) 3·4:2

Решаем примеры:

• \( 4 \cdot 2 + 4 = 8 + 4 = 12 \)
• \( 6 \cdot 2 + 6 = 12 + 6 = 18 \)
• \( 8 \cdot 3 = 24 \)
• \( 7 \cdot 3 = 21 \)
• \( 18 - (15 - 7) = 18 - 8 = 10 \)
• \( 40 + (9 + 13) = 40 + 22 = 62 \)
• \( 6 \cdot 3 : 2 = 18 : 2 = 9 \)
• \( 3 \cdot 4 : 2 = 12 : 2 = 6 \)
