You expand the parenthesis out first. Then simplify the rest.
Yes, and parenthesis are the first thing you solve.
Parenthesis
What I mean by this equation is: x^3-2x^(x-2.5)+x^(x^x)
You square the number in the parentheses.
sin(arcsin(2/3)) = 2/3, since sin is the inverse function of arcsin.

tan(sec-1(5/2))Start with sec-1(5/2), which is the same as cos-1(2/5). So there is a right triangle, where the side adjacent the angle is 2, and the hypotenuse is 5. Solve for the opposite side: sqrt(5² - 2²) = sqrt(21).Tangent is opposite over adjacent, so the answer is sqrt(21)/2

7a=2(-10)........................................answer is 20/7
To solve (184 + 243 + 808) - (109 + 72 + 84) evaluate the parentheses first: (184 + 243 + 808) - (109 + 72 + 84) = 1235 - 265 = 970
Parentheses is when you are doing an equation, and you solve the problem.
