It means find the value of the expression. It cannot be simplified in the way that algebraic expressions usually are.
i^1=i i^2=-1 i^3=-i i^4=1 and so forth 15 divided by 4 leaves a remainder of 3 i^3=-i
f+4(f-2)
2 to the fourth x 2 = 2 to the fifth = 32

The simplify of 2 times 2 take away 2 equals 2. This is a math problem.
It means find the value of the expression. It cannot be simplified in the way that algebraic expressions usually are.

2+2 = 2*2 = 2^2 all simplify to 4. But there is no special name for the three expressions.
To simplify an expression you must combine the variables and the constants. Then write the simplified version of the expression so that the expression isn't solved, just simplified. 1a+2(a+5)=2a+7
i^1=i i^2=-1 i^3=-i i^4=1 and so forth 15 divided by 4 leaves a remainder of 3 i^3=-i
7+2n
It can be factored as 18(5-2x^2)
f+4(f-2)
