Question

What is 2.3 x 2.3 and plz give a step-by-step explanation

Answer 1

5.29

Explanation:

1. Set up the equation 2.3x2.3 on top of eachother like so,

`2.3\\ x2.3`

We will be working right to left.

2. Then we must create the first line of numbers.

a. Mulitply 3x3=9

b. Multiply 3x2=6

This makes the first line of numbers 69.

3. For the second line of number do much of the same.

a. First add a zero under 9 to offset this new line.

b. Then multiply 2x3=6

c. Then 2x2=4

4. Finally add the two number together.

`69+460=5.29`

5. Count up the decimal places in both factors combined, then moved the decimal sign left that many times.

This will result in our answer 5.29.
