Question

If 10 x 2 means 5, 10 divided by4 means14, 10+4 means 6 and 10 - 4 means 40 then 10 x 5 divided by 4 + 3 - 2

Answer 1

10 x 2 = 5

We can see that x means ÷.

10 ÷ 4 = 14

We can see, ÷ means +.


10 + 4 = 6

Hence, + means -.

10 - 4 = 40..

- means x...


10 x 5 ÷ 4 + 3 - 2

is 10 ÷ 5 + 4 - 3 x 2

= 2+ 4 -6

= 0.....

Answer 2

Answer:

Required answer is 0.

Step-by-step explanation:

Given, 10 x 2 means 5, 10 divided by4 means14, 10+4 means 6 and 10 - 4 means 40

So,It is clear that x means ÷ , ÷ means + , + means - and - means × .

Now,10 x 5 divided by 4 + 3 - 2

$10 \div 5 + 4 - 3 \times 2$

By BODMAS rule,

Bracket - Of - Division - Multiplication - Addition - Subtraction

So,

$2 + 4 - 3 \times 2 \\ = 2 + 4 - 6 \\ = 6 - 6 \\ = 0$

This is a problem of Algebra.

Some important Algebra's formulas:

${(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2} \\ {(x - y)}^{2} = {x}^{2} - 2xy + {y}^{2} \\ {(x + y)}^{3} = {x}^{3} + 3 {x}^{2} y + 3x {y}^{2} + {y}^{3} \\ {(x - y)}^{3} = {x}^{3} - 3 {x}^{2} y + 3x {y}^{2} - {y}^{3} \\ {x}^{3} + {y}^{3} = {(x + y)}^{3} - 3xy(x + y) \\ {x}^{3} - {y}^{3} = {(x - y)}^{3} + 3xy(x - y) \\ {x}^{2} - {y}^{2} = (x + y)(x - y) \\ {x}^{2} + {y}^{2} = {(x - y)}^{2} + 2xy \\ {x}^{2} - {y}^{2} = {(x + y)}^{2} - 2xy \\ {x}^{3} - {y}^{3} = (x - y)( {x}^{2} + xy + {y}^{2} ) \\ {x}^{3} + {y}^{3} = (x + y)( {x}^{2} - xy + {y}^{2} )$
