The four basic mathematical operations are:

Addition, subtraction, multiplication and division

Addition

Adding two (or more) numbers means to find their sum (or total). The symbol used for addition is '+'.

For example, 5 + 10 = 15

This is read as five plus ten is equal to fifteen or simply, five plus ten is fifteen.

Example 1

Find the sum of 9 and 8.

Solution:

9 + 8 = 17

Addition of Large Numbers

To add large numbers, list them in columns and then add only those digits that have the same place value.

Example 2

Find the sum of 5897, 78, 726 and 8569.

Solution:

The sum is 15,270.

Note:

Write the numbers in columns with the thousands, hundreds, tens and units lined up.

7 + 8 + 6 + 9 = 30. Thus, the sum of the digits in the units column is 30. So, we place 0 in the units place and carry 3 to the tens place.

The sum of the digits in the tens column after adding 3 is 27. So, we place 7 in the tens place and carry 2 to the hundreds place.

The sum of the digits in the hundreds column after adding 2 is 22. So, we place 2 in the hundreds place and carry 2 to the thousdands place.

Subtraction

Subtracting one number from another number is to find the difference between them. The symbol used for subtraction is 'โ'. This is known as the minus sign.

For example, 17 โ 8 = 9

This is read as seventeen take away eight is equal to nine (or seventeen take away eight is nine). Also, we can say that 17 minus 8 is 9.

Example 3

Subtract 9 from 16.

Solution:

16 โ 9 = 7

Subtraction of Large Numbers

To subtract large numbers, list them in columns and then subtract only those digits that have the same place value.

Example 4

Find the difference between 7064 and 489.

Solution:

Using either the Equals Addition Method or the Decomposition Method, we find the answer is 6575.

Note:

Use the equals addition method or the decomposition method.

Line up the thousands, hundreds, tens and units place values for the two numbers when placing the smaller number below the larger number as shown above.

Multiplication

Multiplication means times (or repeated addition). The symbol used for multiplication is 'ร'.

For example, 7 ร 2 = 14

This is read as seven times two is equal to fourteen or simply, seven times two is fourteen.

Division

Division 'undoes' multiplication and involves a number called the dividend being 'divided' by another number called the divisor. The symbol used for division is 'รท'.

Example 9

Calculate 48รท8.

Solution:

The answer is 6.

Summary

The four basic mathematical operations are:

Addition, subtraction, multiplication and division

Adding two (or more) numbers means to find their sum (or total).

Subtracting one number from another number is to find the difference between them.

Multiplication means times (or repeated addition). A product is the result of the multiplication of two (or more) numbers.

Division 'undoes' multiplication.

This game is specifically designed for starters. Text fonts, graphics, sounds, questions and answers are all designed professionally for the best training experience.

It is very good for kids and also for elders to refresh brain activities.

It is a brain refresher game, teacher game, good for educational practices.

Only four basic operators have been added intentionally to not let any confusion.

The game is focused on the four basic mathematical operations. Addition, Subtraction, Multiplication and Division.

Montessori math teaching.

All addition and subtraction questions are being generated at run time as 2 digit unique questions. Multiplication and division questions are being generated at easy level. Multiplication operands have single digits. And all divisions are exact divisions.
