Explanation

The chapter demonstrates multiplication by breaking the multiplier into tens and ones. For 18×418 \times 4: Break 18 into 10 + 8. Then 10×410 \times 4 = 40 and 8×48 \times 4 = 32. Total = 40 + 32 = 72 cupcakes. This method makes multiplication easier by using known facts.

Solution Steps

  1. Step 1: Total cupcakes = 18 boxes × 4 cupcakes per box

  2. Step 2: Break 18 into 10 + 8

  3. Step 3: 10×410 \times 4 = 40 cupcakes

  4. Step 4: 8×48 \times 4 = 32 cupcakes

  5. Step 5: Total = 40 + 32 = 72 cupcakes
