=

The equality symbol, or =, means “the same as” or “the answer is”.

Another example would be “3+1=4” which is saying that 3+1is “the same as” 4 or 4 “is the answer” for “3+1”.

For Example “the same as” can look like “2=2”, which is saying “two is the same as two”...they are equal. 2

The Addition + Symbol +

The addition symbol or +, is used in order to say “plus” or “a number and another number put together”. For example 2+2 is saying that you have two and you are “adding” two more. If you are using objects it would be the same thing as saying you have two apples and get two more.

Let’s say your teacher gives you two stars on a test, and one the next test you get three more, how many stars do you have total?

** + *** =

*****

You had two, you add three, and you now have a total of five.
