The Babylonians used different formulas. They had different purposes the first one was to make multiplication easier, the second shows that to multiply number the only thing you need is the table of squares.
ab = [(a + b)2 - a^2 - b^2]/2
ab = [(a + b)^2 - (a - b)^2]/4
For division they based on the fact that : a/b = a × (1/b)

Applications in daily life
- Going shopping: x/y
- Simple interest: A=P(1+R)^T
- Loans: P=LR/(1-(1+R)^-T
story: PI (π)
Pi was invented because mathematicians noticed that when a person divided the circumference of a circle by it's diameter, the result would be the same. It would be a never ending number with no kind or pattern, pi. Like pi never ends, it can never be wriiten completely so we use the sign, π, or we say 3.14.
