Addition of Multi-Digit Whole Numbers (Part 1)

The video tutorial explains the standard method for adding numbers by aligning them according to their place values. It demonstrates the process using the example of adding 945 and 36. The tutorial covers aligning numbers from right to left, adding digits in the ones place with carrying over, and then proceeding to the tens and hundreds places. The final result of the addition is 981.

What is the first step in the standard method of addition?

• Subtract the smaller number from the larger one

• Add the numbers without aligning

• Align the numbers from left to right

• Align the numbers from right to left

When adding 945 and 36, what do you do with the sum of the ones place if it exceeds 9?

• Carry it over to the tens place

• Ignore the extra digit

• Subtract it from the tens place

• Add it to the hundreds place

In the example of adding 945 and 36, what is the sum of the tens place after considering the carry?

• 6

• 7

• 8

• 9

In the standard method of addition, what is the purpose of carrying over a digit?

• To avoid using a calculator

• To simplify the subtraction process

• To ensure the correct sum in the next higher place value

• To make the addition process faster

What is the final result of adding 945 and 36 using the standard method?

• 981

• 985

• 991

• 975
