4 Mental Arithmetic Techniques to Calculate 10x Faster
Bypass scratchpad latency by mastering these 4 mental math shortcuts used by competitive math athletes.
School teaches right-to-left addition (carrying ones). Mental math champions calculate from left-to-right by evaluating hundreds and tens first.
To subtract any number from 1,000 in your head, apply the rule: "Subtract all digits from 9, and the last digit from 10".
When multiplying a number ending in 5 or 0.5, double one factor and halve the other to simplify the multiplication instantly.
Simplify long division by breaking divisors into factors (e.g. dividing by 12 is dividing by 4 then by 3).
