v “I have looked at the SQUARE NUMBERS to find patterns and Formulas”

Example : Click on my link to see a graph : ADB Square

v “The SQUARE NUMBERS graph is a curve”

v “When you multiply a whole number by 10, you can just put a [0] on the end. But you have to be careful with decimal numbers to make sure the decimal point is in the correct place, so the NUMBERS have moved to the <LEFT (decimal to the RIGHT>) and the answer is BIGGER.”

Example : 9 x 10 = 90 6.37 x 10 = 63.7 1.5 x 10 = 15.0

v “If you use the signs for [ LESS THAN < ] and [ GREATER THAN > ], remember the SMALLEST END of the arrow always points at the SMALL number.”
