Simple Steps in answering a mathematics question:

• Find all data (information) in the question
• Find the formula that connects the data
• Apply the formula and by manipulation obtain the answer

Question: Calculate the diameter of a circle with circumference 44 cm? Take Pi=22/7

Solution:

• Find all data (information) in the question:
  Circumference, C=44cm, radius=r cm, diameter=d cm
• Find the formula that connects the data:
  Formula: C= 2*Pi*r
• Apply the formula and by manipulation obtain the answer:
  Manipulation: We know that d=2*r, then C=(2*r)*Pi=d*Pi.
  
  Now by subject of formula d = C/Pi
                                              = 44/22/7   
                                              = 44*7/22
                                              = 14 cm

Remark:

• The first step requires good reading skills to locate the data.
• The second step needs the memory to locate the formula. The intellect (discriminative faculty) is used to find the right formula.

The last step depends on speed of the mind to manipulate the formula. This is usually
achieved with a lot of practice.

Try these steps and hope that you will do better in mathematics. Kindly waiting for your views.
