The solution to the first expression - 7+3(9-4)^2÷5 is given as 22.
To get the answer correctly, one must follow rudimentary rules of operations which are coined into the acronym BODMAS.
What is BODMAS?
This is the order in which mathematical operations must be executed.
B = Bracket
O = Orders (that is Powers, Indices or roots)
D= Division
M = Multiplication
A = Addition
S = Subtraction
Now lets see how we got 22 from the first set of operations:
Operation 1 (Example)
7+3(9-4)^2÷5 =
7+3 (5)^2÷5=
7+3 * 25÷5 =
7+3*5=
7+15=
22
Following the BODMAS rule and the example in Operation 1 above, we can state the remaining answers as follows:
Operation 2
12/3-4+7^2 = 49
Operation 3
(7-3)×3^3÷9 = 12
Operation 4
5(7-3)^2÷(6-4)^3-9 = 1
Operation 5
3×(7-5)^3÷(8÷4)^2-5 = 1
Operation 6
9+(3×10)/5×2-12 = 9
