Algebra Class 11 Q 1

Algebra Class 11 Question 1

Dear Students,

From today I am going to start Algebra Class 11.

Here we go.

Question 1:

If a x b = 12 and b x c = 9.

Find the value of min(a+b+c).

We suppose a = -12 and b = -1 we get = 12 and - x - = +.

and b x c, please note that in the above equation we supposed b = -1,

then b = -1 and think how much we have to multiply so that we get the answer 9, yes that is,

b x c
-1 x -9 = 9

next step

we have to find min(a+b+c)

putting values we get

(a+b+c) = -12 + -1 + -9 = -22.

so we can say (a+b+c) = -22.

The Maths Operation Rules BODMAS

Dear Viewers, today I am going to teach you about the Math Rule.

What do you do when you have to calculate the following equation?

5 + (4 × 3² + 5)

5+4 = 9, 3² = 9 & + 5

9+9+5=23?? Wrong...

Let me tell you guys about the BODMAS rule.

BODMAS is the rule of Math. BODMAS stands for

B	Brackets first
O	Orders (i.e. Powers and Square Roots, etc.)
DM	Division and Multiplication (left-to-right)
AS	Addition and Subtraction (left-to-right)

Divide and Multiply rank equally (and go left to right).

Add and Subtract rank equally (and go left to right)

Example:

So, the example in the first is solved as

5 + (4 × 32 + 5)
5 + (4 × 9 + 5)		Start inside Brackets, and then use "Orders" First
5 + (36 + 5)		Then Multiply
5 + (41)		Then Add
5 + 41		Brackets completed, last operation is add
46		DONE !

It's easy just follow the rules. Math is all about rules.

Thanks for viewing! Have a good Math!
