How do you use the standard algorithm to add 453 + 282?

• • I line the numbers up by place value and add them one step at a time, starting with the least value, the farthest to the right. When I get to 5 + 8 = 13, I have to regroup the 1 and add it to the hundreds place. The answer is 735.

• • I add the numbers up them one step at a time, starting with the highest value, the farthest to the left. When I get to 5 + 8 = 13, add it all together The answer is 1335.

• • I subtract the numbers one step at a time, starting with the highest value, the farthest to the left. When I get to 5- 8 = 3 subtract it all. The answer is 35.

​

is a series of steps we follow to get an answer​

Answer explanation

line the numbers up by place value with the greater number on top. Then I subtract each place value, one at a time. Since 8 is greater than 4, I have to regroup 1 from the tens place in 254 to make 10 ones. Now I subtract 14 – 8 = 6, and then subtract 4 – 2 = 2. In the hundreds place, I have 2 – 1 = 1. The answer is 126.
