Create an expression, to equal 13, using any grouping of addition, subtraction, multiplication, and division. you must use all the basic operations at least once (addition, subtraction, multiplication, and division) and you must use at least three sets of parentheses. you can use exponents if you want as well. post your expression to the discussion board.

Step-by-step explanation: Since the question says "... use ANY grouping of the basic operations and let your created expression be equal to 13...",

[10×5] +2 -[5^2+1] ÷ [√4] = 13

There are also three sets of parentheses as requested.

Note: the operations in parentheses are to be solved first before applying the signs which are in front of the parentheses. This expression equals 13.

10 × 5 = 50

50+2=52

[5^2 + 1] = 25+ 1 = 26

52-26 = 26

[√4]=2

26÷2= 13

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
