Let n = the number multiplying by
For 8
(n-n)-n-n-n-n-n-n-n-n / -1
Example: let n = 3
(3-3)-3-3-3-3-3-3-3 = -24 / -1 = 24
Proof
8*3 = 24
For 7
(n-n)-n-n-n-n-n-n-n / -1
Example: let n = 2
(2-2)-2-2-2-2-2-2-2 = -14 / -1 = 14
Proof
7*2 = 14 Alternatively: Let n and m represent the numbers to multiply together Formula is m / ( 1 / n) i.e. to multiply n=3 by m=8 x = 8 / ( 1 / 3) = 24
You can't. Multiple is how you do multiplication
If you really wanted to do this, you could simulate multiplication with repeated addition.

Explain the addition and multiplication properties of inequalities
It can also include addition and multiplication using negative and positive numbers.

I memorized the multiplication table in fourth grade.
By using repeated addition. Consider two numbers a and b. If you want to find a*b then you can add the numbers repeatedly in a loop to get the product. Eg:product = a;for( i=1; i
3 + 4 * 5 = 23 Remember that multiplication must be carried out before addition.
