To insert grouping symbols one must remember that the math problem in the parenthesis must be completed first. The grouping should look like this: 4(6-2)+7= 23.
*Order of operation* #1 Work inside grouping symbols; -grouping symbols include parenthesis ( ) brackets [ ] and fraction bars. #2 Multiply and divide in order from left to right. #3 Add and subtract in order from left to right. P-parenthesis E-exponets M-multiplication D-division A-addition S-subtract
Evaluate the innermost grouping symbol first and make your way outwards.
Numerical Expression
There are different symbols for multiply, dividing and subtracting. You can use the symbols like "x, / and -".
(7+4)x6=66
That type of sentence is called a mathematical expression.
The grouping of symbols and number of 4 times 6 subtract 2 plus 7 equals 23 would look like 4(6-2)+7=23. Remember the problem with the in parenthesis should be completed first.
Grouping symbols are symbols such as parentheses or brackets, that indicate that the operations within them should be done first. When an expression contains more than one pair of grouping symbols, the computations in the innermost grouping should be done first.

Evaluate the innermost grouping symbol first and make your way outwards.
Grouping symbols are parentheses such as {}, (), []. They need to be evaluated before other operations. If there are a number of nested parentheses, they must be evaluated starting with the innermost.
