Horizontal addition helps with mental math. It makes it easier for us to compute the math problem by breaking the equation down into blocks of numbers. This should all take place in one horizontal line.
For example, let’s take 334+632.
First add the hundreds: 300 + 600 = 900
Second add the tens: 30 + 30 = 60
Lastly, add the units: 4 +2 = 6
Therefore, horizontal addition looks like this: 334 + 632 = 900 + 60 + 6 = 966
