is it possible to reduce any mathematical operation to a process of simply adding something

for instance,

mulitiplication can be reduced to addition

e.g.

2*3 = 2+2+2

division

e.g.

3/2 = 3*1/2 = 0.5+0.5+0.5

exponents

e.g.

2^3 = 2*2*2=2+2+2+2

is calculus, geometry, linear algebra, stochastic calculus etc. in the end nothing else then addition or subtraction of numbers in a systematic way?
