Question

What and how to use brackets 1+4×5×6÷7= ?

Answer 1

Hey friend!

While doing operations in mathematics , we have to follow BODMAS RULE

BODMAS=
________

BRACKET
OF
DIVISION
MULTIPLICATION
ADDITION
SUBTRACTION

This is the order of which operation should be first.ln a given mathematical problem ,first we have to open brachets by solving the operations inside bracket ,then of (which is equal to the operation of multiplying ,then division and so on.


Now the given question is

1+4*5*6/7=?
Now lets solve it using bodmas rule.
Here there is no brackets.
No of
Next there is division.lets operate it first
6/7
Since its not completely divisible ,let us keep them as fraction itself.
Next multiply:
4*5*6/7
=20*6/7
=120/7

Next add
1+120/7
let us make denominators same
i.e.,
1+120/7
=7/7+120/7
=127/7
=18.14
