Adding Fractions Step 1: Make sure the bottom numbers
(the denominators) are the same, if not find the LCM (Least Common Denominator).
Step 2: Add the top numbers (the numerators), put the answer over the denominator. If there is two fractions that have the same denominator then keep that number the same.
Step 3: Simplify the fraction (if needed).

Subtracting Fractions
Step 1. Make sure the bottom numbers (the denominators) are the same if not find the LCM.
Step 2. Subtract the top numbers (the numerators). Put the answer over the same denominator.
Step 3. Simplify the fraction.

Multiplying Fractions
1. Multiply the top numbers (the numerators). 2. Multiply the bottom numbers (the denominators). 3. Simplify the fraction if needed.

Dividing Fractions Step 1. Turn the second fraction (the one you want to
divide by) upside-down (this is now a reciprocal). Step 2. Multiply the first fraction by that reciprocal
Step 3. Simplify the fraction (if needed).

Adding decimals Write down the numbers, one under the other, with the
decimal points lined up. Put in zeros so the numbers have the same length. Then add normally, remembering to put the decimal
point in the answer.

Subtracting Decimals
Write down the two numbers, one under the other, with the decimal points lined up.
Add zeros so the numbers have the same length. Then subtract normally, remembering to put the
decimal point in the answer.

Multiplying Decimals
Multiply normally, ignoring the decimal points.
Then put the decimal point in the answer - it will have as many decimal places as the two original numbers combined.

Dividing Decimals Use Division or Long Division (ignoring the decimal
point). Then put the decimal point in the same spot as the
dividend (the number being divided).
