its not different
Arithmetic can be written as two different products of prime numbers. haha
Number theory explains why arithmetic works.
arithmetic starts with m while number theory starts with n
Generally you would start with number theory, then arithmetic.
the main branches of mathematics are algebra, number theory, geometry and arithmetic.

It is different.
At the simple level: Arithmetic. More complex level: Number theory. But NOT numerology which is not a science but superstition.
Number theory (or arithmetic) is a branch of pure mathematics devoted primarily to the study of the integers, sometimes called "The Queen of Mathematics" because of its foundation place in the discipline.en.wikipedia.org/wiki/Number_theor
H. Halberstam has written: 'The uses of arithmetic' -- subject(s): Arithmetic 'Analytic Number Theory' 'Sieve methods' -- subject(s): Sieves (Mathematics)
Mathematics (math) is a broad field of endeavour, which includes arithmetic. Arithmetic is the part which deals with numbers (and their interactions) only. Other math fields are Number Theory, complex numbers, graph theory, differential calculus, many others.
Arithmetic is one small part of mathematics. The latter includes algebra, calculus, geometry and trigonometry, probability and statistics - all of which you will come across during school. Then there are others such as game theory, decision thoery, linear programming, number theory etc most of which you probably will not come across unless you choose to study mathematics at a higher level.
