Multiplying by 10, 100, 1000
Shortcut: Multiply by 10: add one zero. 47ร10=470. Multiply by 100: add two zeros. 47ร100=4700. Multiply by 1000: add three zeros. 47ร1000=47000. WHY? Because place values shift left: 47 โ 4 hundreds 7 tens (ร10). This rule makes mental multiplication very fast! Use it: 25ร40 = 25ร4ร10 = 100ร10 = 1000.
