Can you recall how to use a vertical algorithm with smaller numbers?
Find the value of 4400 + 403.
We can use a vertical algorithm to add numbers, starting with the units column.
If our numbers have more digits, the vertical algorithm is an ideal way to solve a subtraction problem. It's important to line our numbers up by place value, as this video shows.
Find the value of 34\,246+3213.
You can add numbers in any order, but we often add them with the largest number on the top row.
Zero placeholders are important when we write our digits in a vertical algorithm. In the number below, 40\,743 would be written as 4743 if we didn't include a zero placeholder
