Squaring Tricks
Technique
In case of two digit number deduct last digit and add it to another number and then add square of same.
In this technique we simplify the squaring method by making one unit's
digit zero. It is far easy to multiply 50*24 than 54*24. So I used this
technique. Try practice more to become expert in this technique.

Important Formulae
Important Formulae
TIME AND DISTANCE
1. Speed = [Distance/Time],
Time=[Distance/Speed],
Distance = (Speed*Time)
2. x km/hr = [x*5/18] m/sec.
3. If the ratio of the speeds of A and B is a:b, then the ratio of the times taken by them to cover the same distance is 1/a : 1/b or b:a.
4. x m/sec = [x*18/5] km/hr.
5. Suppose a man covers a certain distance at x km/hr and an equal distance at y km/hr. then, the average speed during the whole journey is [2xy/x+y] km/hr.

In this simple trick we need to modify the equation and make the units
digit zero. After all it is easy to multiply when units digit is zero.
For example - Find square of 43
= (43+3) × (43-3) + (3×3)For example - Find square of 43
=(46×40) + 9
= (460×4) + 9
= 1840 + 9 = 1849
