Answer:
Meera bought 6 notebooks from the market and the cost was ` 10 per notebook.
Her sister Seema also bought 7 notebooks of the same type. Find the total money
they paid.
Seema calculated the Meera calculated the
amount like this amount like this
6 × 10 + 7 × 10 6 + 7 =13
= 60 + 70
= 130 and 13 × 10 = 130
Ans. ` 130 Ans. ` 130
You can see that Seema’s and Meera’s ways to get the answer are a bit different.
But both give the correct result. Why?
Seema says, what Meera has done is 7 + 6 × 10.
Appu points out that 7 + 6 × 10 = 7 + 60 = 67. Thus, this is not what Meera
had done. All the three students are confused.
To avoid confusion in such cases we may use brackets. We can pack the numbers
6 and 7 together using a bracket, indicating that the pack is to be treated as a single
number. Thus, the answer is found by (6 + 7) × 10 = 13 × 10.
This is what Meera did. She first added 6 and 7 and then multiplied the sum
by 10.
This clearly tells us : First, turn everything inside the brackets ( ) into a
single number and then do the operation outside which in this case is to
multiply by 10.
Hope it may help you
