Question

how to solve decimal addition pyramid ?

Answer 1

Answer:

To add decimals, follow these steps:

1.Write down the numbers, one under the other, with the decimal points lined up.

2.Put in zeros so the numbers have the same length (see below for why that is OK)

3.Then add using column addition, remembering to put the decimal point in the answer.

Step-by-step explanation:

The way I found was to first subtract the top number by four, and then to divide the result by eight and then subtract one. For example, if you have 12 at the top of this pyramid, you can do twelve -four, and then divide by eight, getting 1. you subtract this by one, you get zero, the correct bottom left corner.
