Proper Usage of the Equal Sign
First, we say and write that two objects are equal or equivalent when they
have the same value. Thus we may write
5 x 4 = 20 and 20/8 = 10/4 = 5/2 = 2½
Second, in high school and college mathematics, we require the full expression
to the left and right of an equal sign, upto the previous or next equal sign,
if any, have the same values. With this convention (followed in this course),
it is wrong to write
2 x (4 x 3) = 12 = 24
even though 4 x 3 = 12 and even though 2 x (4 x 3) = 24. The subexpression
2 x (4 x 3) = 12 is wrong because 12 does not have same value as the full
expression 2 x (4 x 3) before it, namely 24. And of course 12 = 24 is wrong as
12 and 24 have different values.
But is correct to write 2 x (4 x 3) = 2 x 12 = 24.
If your previous teachers in junior high school or primary school have allowed
you to abuse or misuse the equal sign, that was their choice. As a senior high
school instructor and former college instructor, I am telling you how to the
use the equal sign properly. Proper notation is very important in mathematics.
If you write elements of mathematics improperly, you are also reading
mathematics improperly. It my job as a mathematics instructor to use proper
notation and to correct errors in your notation and presentation, errors in
logic and calculation included. Abuse or overuse of the equal sign will be
identified in your written work, and penalized if need-be in order for you to
change your ways.
