Subtracting Large Numbers Using the Standard Subtraction Algorithm

This video tutorial teaches how to subtract multi-digit whole numbers using the standard subtraction algorithm. It covers setting up the problem by lining up numbers correctly, decomposing and recomposing numbers to facilitate subtraction, and using a place value chart to visualize the process. The lesson concludes with a summary of the steps involved in subtracting multi-digit numbers.

What is the first step in the standard subtraction algorithm?

• Use a calculator

• Decompose the tens place

• Line up the numbers to be subtracted

• Subtract the ones place directly

Why is it necessary to decompose numbers in the subtraction process?

• To align the numbers correctly

• To make the numbers larger

• To simplify the addition process

• To handle cases where a smaller digit is subtracted from a larger one

What is the result of 16 minus 8 in the subtraction process?

• 6

• 12

• 8

• 10

What issue arises when subtracting in the thousands place?

• The top number is smaller than the bottom number

• The numbers are already aligned

• There is no need to decompose

• The numbers are too large

What is the final answer to the subtraction problem 343,356 - 24,238?

• 318,000

• 320,000

• 319,118

• 319,000
