Draw a number line and show how to find the difference for 24-6 using the break apart method in this lesson

Subtract two-digit numbers by breaking the second number down into its tens and ones. Subtract the tens from the original first number, find the answer and then subtract the ones from that answer for the final result.Subtract 83 - 24 using the break apart method. Break 24 down into its parts: 20 + 4. Subtract 20 from the original number: 83 - 20 = 63. Subtract 4 from the 63 - 4 = 59. Write that 59 is the final answer.Check the answer by adding it to the second number, 24, to see if it equals the first number: 59 + 24 does equal 83 so the answer is correct.
