Multiplication & Division CFA

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 4 multiplied by 3 (4 x 3) means adding 4 three times (4 + 4 + 4 = 12).

Front

What is division?

Back

Division is a mathematical operation that represents the process of splitting a number into equal parts. For example, 12 divided by 3 (12 ÷ 3) means splitting 12 into 3 equal parts, which equals 4.

How do you find the total number of items when given groups and items per group?

Back

Multiply the number of groups by the number of items in each group. For example, if there are 5 groups with 4 items each, the total is 5 x 4 = 20.

Front

What is the formula to calculate the number of teams formed?

Back

To find the number of teams, divide the total number of students by the number of students per team. For example, if there are 120 students and each team has 12 students, the number of teams is 120 ÷ 12 = 10.

How do you calculate the total cost of multiple items?

Back

Multiply the number of items by the cost per item. For example, if one item costs $5 and you buy 3 items, the total cost is 3 x $5 = $15.

Front

What does it mean to double a number?

Back

To double a number means to multiply it by 2. For example, doubling 6 means calculating 6 x 2 = 12.

Front

What is the expression for adding a number to another number?

Back

The expression for adding a number to another number is written as 'a + b', where 'a' and 'b' are the numbers being added.

Front

How do you represent a number increased by a certain amount?

Back

To represent a number increased by a certain amount, you can use the expression 'x + y', where 'x' is the original number and 'y' is the amount added.

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often remembered by the acronym PEMDAS.

Front

How do you solve a multi-step problem involving addition and multiplication?

Back

Follow the order of operations: first perform any multiplication or division, then perform addition or subtraction. For example, in the expression 2 + 3 x 4, first calculate 3 x 4 = 12, then add 2, resulting in 14.
