Divide Using Mental Math

The World of Division

Explore the concepts and applications of division in this fascinating presentation. Learn how division can be used to solve problems and understand the world around us. Discover the wonders of division and its importance in various fields.

The World of Division

• Division is a mathematical operation that splits a number into equal parts.
• It is denoted by the ÷ symbol.
• It involves a dividend (number being divided) and a divisor (number dividing the dividend).
• The result of division is called the quotient.
• Division can be used to solve problems involving sharing, grouping, or finding equal parts.

Multiple Choice

What is the symbol used to denote division?

• +

• -

• *

• ÷

Division Symbol

Trivia: The symbol used to denote division is ÷. It is also known as the division sign or obelus. This symbol was first used in the 17th century by Swiss mathematician Johann Rahn. It represents the operation of dividing one number by another. +, -, and * are not used to denote division.

The Long Division Method

The long division method is a way to divide large numbers. It involves dividing the dividend by the divisor, writing the quotient above the division bar, and multiplying the quotient by the divisor to get the product. Then, subtract the product from the dividend to get the remainder. Repeat these steps until there is no remainder. Finally, write the quotient as the answer.
