Math Time
Order of Operations
Operators
- are binary; unary ones exist (e.g. negation)
Commutative Law
- beep beep: think commuting
- For & can re-arrange operands; you’ll get the same answer
- Not for or !
Identity
- something that is the same as another thing
- can be proved
- used in math to re-write equations so that they are easier to understand/solve/use
Identity Elements
- a number that when used with an operator, leaves the other number unchanged
- for & the identity element is 0 (e.g.
2 0 = 2
;3 0 = 3
.) - for & the identity element is 1 (e.g.
3 1 = 3
;9 1 = 9
.)
