Squares and Square Roots Tables - JSS2 Mathematics Lesson Note

Squares: When you multiply a number by itself, you get its square. For example:

3/2=3×3=9

(−4)^2=(−4)×(−4)=16

Square Roots: The square root of a number is the value that, when multiplied by itself, gives the original number. For example:

The square root of 9=3 because 3×3=9

The square root of 16=4 because 4×4=16

Tables: These are organized lists showing squares and square roots of numbers. They help in quickly finding these values without calculating each time.
