This activity is about addition of numbers with two decimal places in columns with carrying.
Add the numbers together.

The answer is 256.81
Can you see that this is just the same as doing column addition with numbers that are not decimals? The only difference is that we need to remember to line up the decimal points when writing out the calculation, and include it in our answer!
