1. 3 × 4 + 12 ÷ 6
= 12 + 12 ÷ 6
= 12 + 2
= 14
2. 3! + 4!
= 3 × 2 × 1 + 4 × 3 × 2 × 1
= 6 + 4 × 6
= 6 + 24
= 30
Penjelasan dengan langkah-langkah:
3 × 4 + 12 ÷ 6
= (4 + 4 + 4) + 2
= (8 + 4) ÷ 2
= 12 ÷ 2
= 6
.
3! + 4!
= (3 × 2 × 1) + (4 × 3 × 2 × 1)
= (6 × 1) + (12 × 2 × 1)
= 6 + (24 × 1)
= 6 + 24
= 30
