Answer:
÷
Explanation:
The order of operations: Bracket, Of, Division, Multiplication, Addition ans Subtraction.
The order of operations are:
1.B-------->Brackets-order: bar/vinculum,(),{},[]
2.O-------->Of
3.D-------->Division
4.M-------->Multiplication
5.A-------->Addition
6.S-------->Subtraction
Thus,we may remember 'BODMAS' as a rule where 'O' stands for Of.
Any expression within the brackets must be evaluated first, before it undergoes any operation outside the bra kets.
The order of brackets is square brackets,braces or curly brackets,parenthesis or circular brackets,bar or vinculum and these are removed from within.
- If the expression within the brackets is preceded by a '+' sign then we can remove the brackets without changing the sign of any term of the expression.
- If the expression within the brackets is preceded by a '-' sign then we can remove the brackets by changing the sign of each term of the expression.
