Can we construct the times-14 table by splitting and doubling? Try!

Correct Answer

Yes, the times-14 table can be constructed by doubling times-7 products.

Explanation: Since 14=2×714 = 2 \times 7, any number multiplied by 14 equals double that number multiplied by 7.

Examples:

1×14=2×7=141 \times 14 = 2 \times 7 = 14 2×14=2×14=282 \times 14 = 2 \times 14 = 28 3×14=2×21=423 \times 14 = 2 \times 21 = 42 4×14=2×28=564 \times 14 = 2 \times 28 = 56

Each times-14 product is double the corresponding times-7 product.
