Please post your test problems this way:

  • Problem:(answer,level of difficulty(easy, medium, hard))
  • Example 2x=6: (x=3,easy)
  1. (5 + x)^2 where x=4 (easy)
  2. 3*3+4 (easy)
  3. 2x–(2x+3) where x=.5 (medium)

Section A (5 marks)[edit]

Evaluate the following expressions.

  1. 24 \div 6 - 7 =
  2. (5 + 3) \times 6=
  3. \frac{16+14}{5} - 3=
  4. \frac{36}{4 - (-2)}+5=
  5. (\frac{2 \times 27}{9})^2=

Section B (5 marks)[edit]

Evaluate the following expressions.

  1. 9+3^2=
  2. 3+ \frac{20}{2^2} =
  3. \frac {2(3+4)}){94^0}=
  4. 20 - 2(\frac{96}{4^2})=
  5. -4 + 5(\frac{56+7}{3^2}) - 1 =

Section C (5 marks)[edit]

Evaluate the following expressions when w=4, x=5, y=6 and z=7.

  1. 3x+2y+z=
  2. \frac{w^2}{y+2}+2z=
  3. 2(\frac{x^2+3}{w})-(2y-z)=
  4. (6-3)(\frac{2w-x}{z-4})+(3y-4)=
  5. 3^2(2w^0)(\frac{wx}{y-2})-z=

Section D (5 marks)[edit]

Evaluate the value of x in the following equations with the given value of y.

  1. 4x+3y=18 (given y=2)
  2. \frac{2x}{y+1}+4=20 (given y=3)
  3. 2(\frac{2x-2}{y-3}+8=6^2 (given y=7)
  4. 3^3+2^0+3x-2y(\frac{18}{2})=97 (given y=3)
  5. [5(2x-3)]^2=y+6 (given y=19)
