Multiplication, using the x symbol, can show the same idea as repeated addition (of equal amounts), using the + symbol. The symbol for division, or sharing into equal groups, is ÷. It’s called the division symbol.

The equals sign (British English, Unicode Consortium) or equal sign (American English), formerly known as the equality sign, is the mathematical symbol =, which is used to indicate equality in some well-defined sense.

×

The number that is being divided (in this case, 15) is called the dividend, and the number that it is being divided by (in this case, 3) is called the divisor. The result of the division is the quotient.

The division slash ⟨ ∕ ⟩, is used between two numbers to indicate division (e.g., 23 ÷ 43 can also be written as 23 ∕ 43). This use developed from the fraction slash in the late 18th or early 19th century. The formatting was advocated by De Morgan in the mid-19th century.

The steps are more or less the same, except for one new addition:

1. Divide the tens column dividend by the divisor.
2. Multiply the divisor by the quotient in the tens place column.
3. Subtract the product from the divisor.
4. Bring down the dividend in the ones column and repeat.

When teachers talk about division facts, they mean the division number sentences related to times tables. Therefore: 30 ÷ 3 = 10, 27 ÷ 3 = 9 and 24 ÷ 3 = 8 are all division facts for the three times table.

We can solve this type of problem using an organizer, repeated subtraction, and/or a multiplication sentence with an unknown factor. “Let’s review the different types of division problems. Remember there are two types of division problems: sharing and grouping.” Give each student an index card.

Division allows us to divide or ‘share’ numbers to find an answer. For example, let’s consider how we would find the answer to 10 ÷ 2 (ten divided by two). This is the same as ‘sharing’ 10 sweets between 2 children. Both children must end up with the same number of sweets.

The difference between equal sharing and equal grouping boils down to what the quotient represents. When sharing, the quotient represents the quantity of shared objects in each group. When grouping, the quotient represents the amount of groups within the shared quantity.

Equal groups – same number of objects in each group. Factor – number of groups and the number in each group. Equation – a statement that two expressions are equal, for. example 5 x 4 = 20. Divide – separate into equal groups.

Equal sharing problems are partitive division problems where the amount in each group is unknown. Number of. groups. Amount in. each group.

Addition-sum, altogether, all, in all, together, total, total number, add, increase, increased by, more than. Subtraction-minus, greater than, take away, fewer than, less than, subtract, decreased by.

An arrangement of objects, pictures, or numbers in rows and columns is called an array. Arrays are useful representations of multiplication concepts (among other ideas in mathematics). This array has 4 rows and 3 columns. It is a 5 by 4 array. Notice that the rows in each array are equal in length.
