2.1 Introduction to the ngazi method
Suppose you are trying to calculate the function f(x)= m16.
The method you would use is probably the normal method we always use for calculating exponential functions. You would multiply m by itself 15 times to get m16.
f(x)= m×m×m×m×m×m×m×m×m×m×m×m×m×m×m×m = m16.
However, this method is tedious, time-consuming and inefficient.
Now let us use the ngazi method to calculate this function. I will calculate it first, then I will explain after the calculation.
