I have experience teaching in my own country about the subject.

I achieved an A in O level Mathematics.

The quadratic equation is x=(-b+-SQRT(b^2-4ac))/2a. In this instance, a = 3, b = 2, and c = 15. Simply putting the numbers in place of the letter counterpart, gives an answer of 1.93 and -2.59 to two deci...

First, my approach is to ask student to count the squares on the area under a curve. This process is tedious, and only gives an estimation. Next, I show them the formula to do integration, and immediately...

First of all, you would label the equations, so let's call 3x +4y = 18 equation A, and 5x - 2y = 4 equation B. Then you would try to find a way to eliminate one of the variables (either x or y). We can do...
