Addition is fun!

Addition is ... ... bringing two or more numbers (or things) together to make a new total. Here 1 ball is added to 1 ball to make 2 balls:   Using Numerals it is:      1 + 1 = 2       And in words it is:   "One plus one equals two" Example: When we add  2  and  3  we get  5 . We can write it like this: 2 + 3 = 5 Swapping the position of the numbers we are adding still gets the same result! 3 + 2 = 5 ... also ...   2 + 3 = 5 More Examples: 5 + 1 =  1 + 5  = 6 7 + 11 =  11 + 7  = 18 4 + 100 =  100 + 4  = 104 Larger Numbers: Use Addition in Columns To add larger numbers use  Column Addition  :   Names Other names for Addition are  Sum, Plus, Increase, Total And the numbers to be added together are called the " Addends ": For better understanding: https://www.khanacademy.org/math/early-math/cc-early-math-add-sub-...
