I need help with algebra.

answered by Guest

9 × 9 = 81

9 plus itself 9 times equals 81

the nines table goes 9,18,27,36,45,54,63,72,81,90

To check the two numbers add up to 9 for 1-10 multiples

Algebra would be m × m =m^2

^means to the power and the 2 means we are doing it to the power of two [Also known as squaring]

This works because they are both the same number
