## User videos Konst Math: Adding and Subtracting Decimals
Adding and subtracting decimals is very similar to performing the same with any whole numbers. If you know how to add and subtract whole numbers, then you can add and subtract decimals! Just be sure to line up the terms so that all the decimal points are in a vertical line. Konst Math: Adding and Subtracting Fractions
Like fractions are fractions with the same denominator. You can add and subtract like fractions easily - simply add or subtract the numerators and write the sum over the common denominator. Before you can add or subtract fractions with different denominators, you must first find equivalent fractions with the same denominator, like this: Find the smallest multiple (LCM) of both numbers. Rewrite the fractions as equivalent fractions with the LCM as the denominator. Konst Math: Adding and Subtracting Mixed Numbers
The steps are the same whether you're adding or subtracting mixed numbers: Find the Least Common Denominator (LCD), find the equivalent fractions, add or subtract the fractions and add or subtract the whole numbers and write your answer in lowest terms.
