Addition And Subtraction Statement Sums

In statement sum we are given a statement. We have to analyse the statement and then take appropriate action.

Clues To identify Addition:

In the statements when phrases like 'How Many in all?' ' or ' Total numbers of items' or 'Items altogether' etc are given we have to preform addition.Moreover, in addition statements  the answer is always more than the addends.

Clues To identify Subtraction:

In the statements when phrases like 'How Many are left?' ' or ' How many more items' or 'How many less Items' etc are given we have to preform subtraction.Moreover, in subtraction statements  the answer is always less than one of the numbers..

Following steps are required to solve the statement

1. Read the statement carefully

2. Find the values that are given

3. Find the quantity which is required

4. Then perform the process to reach the desired result.

Let us consider the following example;

There are 987 fruits in a basket. Out of which 324 are mangoes and 452 are apples, and the rest are grapes. How many grapes are there?

1. We will first analyse the statement

2. We will find the values that are given

In the question it is given that

There are 987 fruits in a basket. Out of which 324 are mangoes and 452 are apples, and the rest are grapes.

So, No. of fruits in a basket = 987

No. of mangoes =.324

No. of apples = 452

3. We will find the quantity which is required

In the question it is asked that

How many grapes are there?

We know the total number of fruits also the number of mangoes and apples and the remaining are grapes.

So to find number of grapes we will first add the number of mangoes and apples.

Then to find the number of grapes we will subtract the sum of mangoes and apples from the total number of fruits.

We will perform addition to find the no. of mangoes and apples altogether.

324 + 452 = ?

We will perform the required operation

We will now perform subtraction to find the no. of grapes.

987 - 776 = ?

We will perform the required operation

Hence there are 211 grapes in the basket.

Illustration 1: Naman sold 624 chocolates on Monday and 185 chocolates on Tuesday.  How many chocolates dis he sold altogether? Identify the relation that will give the result.
