MATHEMATICS TABLES
Simple Addition Tables: There are two tables for addition of numbers zero through twenty. After the we have learned how to add, we can use the table to check our answers if we are in doubt; it is cheaper than a calculator. We can write on a piece of paper the combinations which give us the most difficulties without the answers; we can say the addition problem and look up the answer on the table until we have the answer memorized. They can use the row across the top and the column down the left side for the addends. The sum is the intersection of a column and a row. This teaches us how to use addends to find a sum.

Complex Addition Tables: This will teach you how to use addends to find a sum. This will also show you the relationship of odd numbers and even numbers. By using the row across the top and the column down the left side, we can see that interchanging the addends doesn't matter; the sum is the same. We might as well learn now the Commutative Law for addition. This law states that if we interchange the addends the answer will be the same. For example: 5 + 3 = 3 + 5; these two mathematical statements equal eight. To have a deeper explanation of this these addition tables click here.
Simple Multiplication Tables: There are three tables for multiplication of numbers zero through twelve. When we are having trouble, we can write those problems on a piece of paper without the answers. Taking one problem at a time, repeat the multiplicand and the multiplier, and the problem's product until we do not have to look up the answer. The multiplication table like the addition table has the answer where the column and row intersect. This teaches us how to use factors (the two numbers being multiplied) to find a product.

Complex Multiplication Tables: Besides having a multiplication table, we will learn about many observations we should be making. By observing the multiplicand and multiplier (also called factors), we will know whether the product is an odd or an even number before we multiply. We will observe that the Commutative Law also applies to multiplication. For example: 6 x 8 = 8 x 6; these two mathematical statements equal 48.

Subtraction with an Addition Table: When learning to add simple numbers, we may also want to learn to subtract simple numbers. We will learn about minuends, subtrahends, and differences. The minuend is the number from which we are subtracting. The subtrahend is the number that we are subtracting from the minuend. The difference is the answer to a subtraction problem. If we add the difference and the subtrahend, we will get the minuend. To get this FREE table click here.
Division with a Multiplication Table: When learning to multiply simple numbers, we may also want to learn to divide simple numbers. We will learn about divisors, dividends, and quotients. The divisor is the number that we want to know how many are in the dividend. The dividend is the number that we are asking how many divisors are within it. The quotient is the answer to a division problem. If we multiply the quotient and the divisor, then add in any remainder, we will get the dividend. To get this FREE table click here.
