Importance of Barckets in math

Hello everyone..!!!

Hope you’re doing well.
Our today’s topic is

Brackets :How to use in equation solution

Here I’m going to explain

what If one don’t place brackets at right positions while solving any equation consisting one or more Functions? what changes comes for not placing brackets? what happens if brackets placed at right place?

So without wasting time I’m starting,

suppose an equation is given

5x+ 4x =9x

but

5x+ -4x =9x,-9x , 1x, -1x

this creates confusion to some learners that from which function the equation will be operated,
so this should be
5x+(-4x) = 5x -4x = 1x or x

similarly,

22+ 6 -8 ×-7 …..?????
this should be written correctly first i.e.
22 + 6 – 8 × (-7)
apply Bodmas rule

22 + 6 – -56
again it should be written correctly

22 + 6 – (-56)

22 + 6 + 56

84.

and in algebra if the equation​ is,

3y + 5 × -x – 6÷ -3 …😒😓

quite confusion ha…!!!
OK, see below,

3y + 5× (-x) -6 ÷(-3)

3y -5x + 6/3

ans .
3y – 5x + 2.

again if

Q. Divide 6x + -4x – 3y by 3.

if we write the above statement like

6x +(-4x) -3y ÷3

then it is totally wrong as instead of the equation only last term i.e. -3y is seems to be divided by 3,
so, we should place suitable Brackets

like

[ 6x +(-4x) -3y ] / 3

now this is explaining itself that the whole equation is divided by 3.

[ 6x -4x -3y] /3

[ 2x -3y ] /3

this is it.
I hope this tutorial of importance of brackets in math, remain helpful for you.
