pls help regarding

Answer 1

Hi friend

1). 80×10×7+5-3.
This que is solve with the help of BODMAS means Bracket, Of, Division, Multiplication, Addition, Substraction.
So firstly we remove bracket then Of then going through sequence which is giving above.
We saw that in this no bracket and no divison. So we solve firstly Multiplication.

=> 800×7+5-3
=> 5600+5-3
=> 5605-3
=> 5602 ans


2). (-6)-[(-48)+(-12)] +(-2)-6
There are three brackets ( ) small bracket. { } middle bracket and [ ] large bracket. Firstly we solve the small bracket then middle and in last large bracket. If there is a symbol of subtraction before the bracket then the symbol is in the bracket change when we remove the bracket like
2-(-5+3) then it change into 2+5-3
Now see ur que 2
Ans is
=> (-6)-[(-48)+(-12)] +(-2)-6
=> (-6)-[-48-12]-2-6
=> -6-[-60]-2-6
=> -6+60-2-6
we also write
=> 60-6-2-6
=> 60-14
=> 46 ans

I think it help u
