Repeated multiplying of the same number may be reduced to a superscript of the amount of times the number appears in the equation. This is read, "to the [#]th power."
n x n x n = n^3
Multiplying a number by itself three times.
n x n x n
Multiplying a number by itself once.
n x n
Any number multiplied by one will result in the original number.
n x 1 = n
Any number multiplied by zero results in zero.
n x 0 = 0
Changing the grouping of factors does not change the product.
(ab)c = a(bc)
Changing the order of factors does not change the product.
ab = ba
Because it represents repeated addition, multiplication may be distributed over subtraction separated by parentheses.
3(4 - 3) = (4 - 3) + (4 - 3) + (4 - 3)
Therefor,
a(b - c) = ab - ac
Altering the order of numbers will yield different results.
a - b =/= b - a
Because it represents repeated addition, multiplication may be distributed over other addition separated by parentheses.
3(2 + 3) = (2 + 3) + (2 + 3) + (2 + 3)
Therefor,
a(b + c) = ab + ac
Added numbers may be grouped in any way with the same result.
(a + b) + c = a + (b + c)
Any number added to zero will always result in the original number.
a + 0 = a
Numbers may be added in any order with the same result.
a + b = b + a
After all other operations have been completed, addition and subtraction equally share the lowermost priority; they must be fulfilled from left to right.
After parentheses and exponents have been fulfilled, multiplication and division equally share the next priority; they must be fulfilled from left to right.
Numbers with exponents must be multiplied before they may be used for other operations.
Operations contained between the symbols ( and ) must supercede other operations.
A remainder occurs when whole numbers do not divide evenly, and is signified with an R.
13/4 = 3R1
Zero may be divided by any non-zero number, and will always result in zero.
0/n = 0
No number may be divided by zero; the result is undefined.
n/0 = ???
Any non-zero number divided by itself is one.
n/n = 1
Any number divided by one remains unchanged.
n/1 = n
Altering the order of numbers will yield different results.
a/b =/= b/a
