Equals sign
The equals sign states that the expressions on its two sides have the same value.

Defining relationship
Read = as “has the same value as.”
The equals sign, =, states that the expression on its left and the expression on its right represent the same value; it may be used in equations and identities.
same value on both sides
What it means
Think of = as a balance statement, not as “the answer comes next.” Both sides must name the same amount. That is why 8 + 4 = 6 + 6 is true, and 12 = 8 + 4 is also true.
Remember it
Read = as “has the same value as.”
Example
For 7 + 5 = 3 × 4, the left side is 12 and the right side is 12, so the equals sign makes a true statement.
Watch for
The equals sign does not mean “calculate now”; it compares the values of the complete expressions on both sides.
Common mix-up
Do not read = as a one-way arrow. You can write 15 = 9 + 6 as well as 9 + 6 = 15.
Exact meaning
The equals sign, =, states that the expression on its left and the expression on its right represent the same value; it may be used in equations and identities.
