Addition is adding a number to another number, say, we have 2 apples and then someone gave us 1 more apple, how many apples I have?Well the answer would be 3.

In mathematics we write it as follows : 2 + 1 = 3 (+ is addition symbol)

Now practice these:

4+7

3+2

5+3

1+27

12+23

5+7

7+7

6+6

8+8

Subtraction is the reverse of addition, we had for example, 6 apples, someone wanted 2 of them so we gave them, how many we have left? It would be 4

again in mathematics we write it: 6-2=4 (- is the subtraction symbol)

Now practice these:

4-3=

2-1=

2-2=

5-3=

11-4=

14-3=

19-7=

35-31=

Multiplication is repeating a number by a specific amount (Ex.another number says it)

like: 2 * 3 (Notice that * is a multiplication symbol) 2*3 (Basically says that 2 is repeated 3 times, so it is like addition 2+2+2=6) So 2*3=6

Now practice these:

3*4=

5*6=

2*10=

3*7=

1*7=

Hope that helped.

Mathematics is the science that deals with the logic of shape, quantity and arrangement. Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports.

Some enjoy it some think it is boring and can not quite grasp it (such as me)
