What mathematical symbols do I need to know?
- Starting with the basic four operations
Addition, plus, sum, total
Subtraction, minus, difference, take away
Multiplication, product, times
Division, divide, share
- Equals signs
Equal to e.g.
Not equal to e.g.
Approximately equal to e.g.
Identical to e.g.
- Inequality signs
Greater than e.g.
Greater than or equal to
Less than or equal to
- Other helpful symbols
Brackets: used to group symbols e.g.
Powers (also called indices or order): repeated multiplication of the base number
Square root: opposite of squaring e.g.
Plus Minus: Used to allow for two distinct answers, often in quadratics
is shorthand for and
e.g. leading to and
Pi: the ratio of the circumference of a circle to its diameter
What do the order of operations BIDMAS or BODMAS mean?
- The order of operations helps when solving simple and complex mathematical problems
- It simply tells us the order to approach a calculation
- Each letter of BIDMAS or BODMAS stands for a different mathematical symbol or operation
Indices or Order
- If there are multiple addition and subtraction symbols these should be worked out in order left to right
First deal with anything inside BRACKETS
Then any powers
Followed by any multiplication or division
Finally dealing with any addition or subtraction
