How to Play the Multiply m and cm Game

1. Read the Problem
   The game shows you a measurement in meters (m) and centimeters (cm), followed by a multiplier (how many of those items you have).
   Example: 4 m 65 cm multiplied by 3.
   

2. Multiply the Centimeters
   Multiply the centimeter number by your multiplier first.
   65 cm × 3 = 195 cm.
   

3. Regroup
   In the metric system, 100 cm = 1 meter.
   Look at your centimeter total. If it is 100 or more, “bundle” the hundreds into meters.
   Since 195 cm contains one hundred, it becomes 1 meter and 95 cm.
   

4. Multiply the Meters
   Now, multiply the original meter number by the multiplier.
   4 m × 3 = 12 m.
   

5. Combine Your Totals
   Add the meters you “carried over” from Step 3 to your meter total.
   12 m + 1 m (carried) = 13 m.
   Final Answer to type in: 13 m and 95 cm.
   

Example:
Problem: 2 m 50 cm × 4
Multiply cm: 50 × 4 = 200 cm.
Regroup cm: 200 cm is exactly 2 meters and 0 cm.
Multiply m: 2 × 4 = 8 m.
Add Carry: 8 + 2 = 10 m.
Result: 10 m 0 cm.
