Example Problems for Math 40 Solving Problems


Solving the below problem using addition, subtraction, multiplication and addition operation in math.

Using Addition Operation in Math

Example 1:

Add 40 and 60?

Solution:

Let us add the given problem.

Write the given whole number 40 first and then write the given whole number 60 second one by one.

40 (addend)

(+)   60 (addend)

--------------

100

--------------

The sum for adding 40 and 60 is 100.

Using Subtraction Operation in Math

Example 2:

Subtract 40 and 10?

Solution:

Let us subtract the given problem.

Write the given whole number 40 first and then write the given whole number 10 second one by one.

40 (minuend)

(-)   10 (subtrahend)

--------------

30 (difference)

---------------

The difference for subtracting 40 and 10 is 30.

Using Multiplication Operation in Math

Example 3:

Multiply 40 and 8?

Solution:

Let us write the given problem as in the below form. Here, 40 is multiplicand and 8 is multiplier.

40 ×

8

----------------

320

----------------

The product for multiplying 40 × 8 is 320.

Using Division Operation in Math

Example 4:

Divide 40 by 10?

Solution:

Let us write the given problem is in form of 40 ÷ 10 and put the divisor on the left side of the division bracket and dividend on the right side of the division bracket.

Check whether the 10 goes into 4 or not. The number 10 cannot go into 4. So that takes the dividend as two digit number. Now the divisor 10 goes into 40 for 4 times. Continue with the division method for the given problem.

10)40(4

0

----------------

40

40

----------------

0

-----------------

The quotient for dividing 40 by 10 is 4.
