Answer 1

⭐Busca tres maneras distintas de resolver estos cálculos:

 

Expresaremos las operaciones de manera distinta:

 

A) 36 × 40 = 1440

1. (30 + 6) × (20 + 20) = 36 × 40 = 1440
2. (18 × 2) × (20 × 2) = 36 × 40 = 1140
3. (9 × 2²) × (5 × 2³) = 36 × 40 = 1140

 

B) 12 × 101 = 1212

1. (12 × 10²) + 12 = (12 × 100) + 12 = 1200 + 12 = 1212
2. 10² × (3 × 2²) + 12 = 100 × 12 + 12 = 1212
3. (6 × 2 × 101/100 × 100) = 1212

Answer 2

A) 36 × 40 = 1440

• (30 + 6) × (20 + 20) = 36 × 40 = 1440
• (18 × 2) × (20 × 2) = 36 × 40 = 1140
• (9 × 2²) × (5 × 2³) = 36 × 40 = 1140

 

B) 12 × 101 = 1212

• (12 × 10²) + 12 = (12 × 100) + 12 = 1200 + 12 = 1212
• 10² × (3 × 2²) + 12 = 100 × 12 + 12 = 1212
• (6 × 2 × 101/100 × 100) = 1212
