Answer:
To improve your mathematical calculation skills, memorize the multiplication tables up through 15, which will make doing calculations in your head a lot easier. Also, try to regularly take speed addition, subtraction, and division tests online so you can get faster and faster at them.
For example, if you are multiplying 125 x 15, you can break this up into two component parts (factoring out, essentially). First, multiply 125 x 10 (1250). Second, divide that answer by 2 (625). Now add both numbers together (1250 + 625 = 1875).[4]
Instead of dealing with writing down the multiplication and work right-to-left, you can realize that you’re looking for 125 x (10 + 5) = (125 x 10) + (125 x 5) = (125 x 10) + (125 x 10 / 2).
By breaking the problem down to one simple calculation of 125 x 10, one division by 2, and one addition, you avoid a trickier multiplication.
Always look for ways to use simpler calculations or memorized multiplication tables, for instance, to simplify a harder calculation.
Understanding these component parts can then be applied to leaving a 15% tip, for example, and all you have to do is move some decimal places afterward.
