This is one of the practice module that was given in my school , can you guys please able to answer the first page of this math questions? so I can have the idea how to answer the second and third page of this module , thank you in advance.
(Operations of functions)
a(x) = x + 5
b(x) = x^2 - 3x + 4
c(x) = - 3x + 4
d(x) = 5x - 3
e(x) 2x^2 - 3
f(x) = x/2 + 3
g(x) 2x-1/x+5

Direction: Perform the indicated operations. Write your answer in the box provided below each number.

1. a(5) + b(2) - c(1) [ ] + [ ] - [ ] = [ ]
2. b(3) - e(2) x d(1) [ ] - ( [ ] × [ ] ) = [ ]
3. f(10) x e(5) ÷ c(4) [ ] × [ ] ÷ [ ] = [ ]
4. e(3) ÷ b(2) + c(1) ( [ ] ÷ [ ] ) + [ ] = [ ]
5. b(5) + g(3) × a(2) [ ] + ( [ ] × [ ] ) = [ ]
6. c(4) x d(1) - f(2) ( [ ] × [ ] ) - [ ] = [ ]
7. g(3) - a(1) ÷ f(1) [ ] - ( [ ] ÷ [ ] ) = [ ]
8. d(3) + e(2) - f(2) [ ] + [ ] - [ ] = [ ]
9. d(4) - b(2) × g(1) [ ] - ( [ ] × [ ] ) = [ ]
10. g(3) - f(2) + b(4) [ ] - [ ] + [ ] = [ ]​
