To evaluate algebraic expressions there is no order. You just need to follow something called pemdas. The way to remember this is
p = please
e = excuse
m = my d = dear
a= aunt
s = sally
So just remember Please excuse my dear aunt sally or pemdas.
P = parentheses (Apply from left tor right)
E = exponent (Apply from left tor right)
M = multiplication (Apply from left tor right)
D = division (Apply from left tor right)
A = addition (Apply from left tor right) S = subtraction (Apply from left tor right)
In solving algebraic expressions, there is an order in which to solve it.
1) perform the operation inside the parenthesis first 2) then perform the operation with the exponents 3) apply multiplication and division from left to right of the equation. 4) apply addition and subtraction from left to right of the equation.
The answer must be a whole number because for example how are you suppose to fit half a child on a bus that can hold 44 people when it already holds that amount.
It will always be a whole number because if there are several left over students they will be put in another bus with more empty seats.
