Multiply by 2-digit numbers: complete the missing steps

key notes :

When multiplying by a 2-digit number, we break the number into tens and ones, multiply separately, and then add the results.


  • Write the numbers in columns (ones under ones, tens under tens).
  • Multiply the ones digit of the 2-digit number with the top number.
  • Write the result in the first row.
  • Multiply the tens digit of the 2-digit number with the top number.
  • Remember to place a zero (0) at the end (since it’s in the tens place).
  • Add the two partial products to get the final answer.

Multiply 236 Γ— 24

Step 1: Multiply by the ones digit (4):

236 Γ— 4 = 944

Step 2: Multiply by the tens digit (20):

236 Γ— 20 = 4720

Step 3: Add the results:

  944
+4720
-----
 5664

βœ… Final Answer: 5664
