Hopefully you know at least how to add (5+4 = 9, etc). If not you should definitely learn to add before you learn to type. Adding whole numbers is the same as adding numbers you learned in kindergarten, with the exception of 0 (but then, a+0 = a for all numbers a).

Say you wanted to subtract 7 from 13.
0 1 2 3 4 5 6 <- 7 <- 8 <- 9 <- 10 <- 11 <- 12 <- 13
Basically, all you do is count down 7 numbers from 13, which takes you to 6.
Now say you wanted to add 8 to 12.
10 11 12 -> 13 -> 14 -> 15 -> 16 -> 17 -> 18 -> 19 -> 20 21 22
All you is go 8 numbers up from 12, which leads you to 20.
add, subtract, multiply, divide
If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. 2.5 -1.4 =1.1 hope this helps and if not yahoo usually has good examples.
In the same way that you subtract and add numbers. Sometimes, though, if the answer is greater than 360 dgrees, you can subtract 360. This is because the angle measure of a whole turn and a bit is the same as the angle measure of the bit.
Word problems have key words, like sum, add, difference, subtract, product, multiply, quotient, divide.
By the signs: 2+2(Add) 2-2(Subtract) +=add -=subtract
add? dont you mean subtract?
you take away one of the whole number=then you add or subtract your fractions=
The same way you would add or subtract whole numbers, leaving the denominators alone.

well that is easy to add two whole numbers like 8+10 is just 18 so you find the total of the two numbers. then to subtract you take it away so 9-4=5 then to check add the 2nd number (in this case 4) to what the sum equals and 4+5=9
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...
