Subtraction Answer

Introduction to subtraction answer:

Subtraction is one of the four basic arithmetic operations; it is the inverse of addition, meaning that if we start with any number and add any number and then subtract the same number we added, we return to the number we started with. Subtraction is denoted by a minus sign in infix notation.

c − b = a

where minuend (c) − subtrahend (b) = difference (a). Now we see about subtraction answer.

About subtraction answer:


In the subtraction, the given parts are named as the minuend and the subtrahend and the resultant answer will be named as the difference. The Minuend which is the first number and the subtrahend is the second number. Thus, we have to subtract the number in this format only.

The Subtraction answer is nothing but the resultant of the numbers which have been subtracted. Let us see one example for the subtraction answer method.

Example:

Subtract the number 1 from 4 and give the subtraction answer.

Solution:

It can be given as (4 - 1). The Following is for the subtraction answer as follows,

4       ->Minuend

-1      ->Subtrahend

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

3      ->Difference

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

Thus, the subtraction answer or the difference can be given as 3.

Way of checking the subtraction answers:

The subtraction answers can be checked or verified by using the technique given below.

The Difference number and the subtrahend number should be added together to give the minuend number.

The above example can be checked as follows,

1       ->subtrahend

+ 3    ->difference

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

4       ->minuend

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

I have recently faced lot of problem while learning basic math problems, But thank to online resources of math which helped me to learn myself easily on net.

Problems for subtraction answer:


Example 1:

Subtract the numbers :(-5 – 6)

Subtraction answer:

Now we are going to subtract the numbers as follows,

(-5 – 6) = -5 + (-6) = -11.

Subtracting 6 is the same as adding a -6.

Thus, we get the subtraction answer as -11.

Example 2:

Subtract the given expressions and find the value of x in the expression:

5x = 6

3x = 2

Subtraction answer:

Now we subtract the two expressions.

5x = 6

- 3x = 2

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

2x = 4

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

Now divide the equation on both the sides we get,

x = 2.

Thus, the subtraction answer for the given expression is 2x = 4 and the value of x is 2.
