1. Mimi_x3

Lol, just study and practice makes perfect!!

2. pokemon23

Can you explain to me absolute value and radicals?

3. Mimi_x3

ANy examples?

4. pokemon23

Well like adding or subtracting absolute value?

5. ParthKohli

You can study Algebra 1 on Openstudy :P

6. ParthKohli

Absolute value... ah very basic stuff.

7. mathslover

PRACTICE MAKES EVERYTHING PERFECT ......

8. pokemon23

Can you guys explain to me? final tomorrow?

9. Mimi_x3

Any questions? Or want me to make some up?

10. mathslover

@pokemon23 first make your fav. topic best and then conc. on the harder topics

11. ParthKohli

Absolute value is the distance of a number from zero in units. Think of a number line.

12. ParthKohli

Both -2 and 2 are 2 units away from zero on a number line, so we may say $$|\pm2| = 2$$

13. ParthKohli

Similarly - $$|\pm n| = n$$

14. samyflashy

absolute value is always positive, except when theres a negative sign at the front - l2l, but first do all procedures between the l l

15. ParthKohli

And $$-|-2| = -2$$ So, $$-|-n| = -n$$

16. ParthKohli

I have a tutorial on absolute value equations and inequalities.

17. ParthKohli

Though it's old and I think you won't comprehend it very well.

18. mathslover

|a+ib| = sqrt{a^2+b^2} lolz it is of complex numbers

19. pokemon23

I would like to see the tutorial?

20. ParthKohli

Sure, I'll link you to it.
