2+2=4

2 + 2 = 4 is a simple math equation that means two things added together is equal to four things. For example, if you have two apples and then you add two more apples, then you have a total of four apples. Another example is if you have two crayons and then you add two more crayons, you now have a total of four crayons. An analogy would be like if you have two pennies in your pocket and then someone gives you two more pennies, you now have a total of four pennies.
