Answer:
5.29
Step-by-step explanation:
1. Set up the equation 2.3x2.3 on top of eachother like so,
[tex]2.3\\ x2.3[/tex]
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.
[tex]69+460=5.29[/tex]
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.
