Quick math(s) question

[Al]

i would be really grateful if someone could help me.


does a + a = 2a or does a+a = a²

i think it equals a². thanks very much!!!!!!

:sohappy:

 

[kal1484]

it would be 2a

if it was (a)(a) then it would equal a2


(sorry can't do the exponant)

Maths was never a strong point but if you substitute "a" for a number you will get your answer.

If "a" = 2 then in your equation a+a=2a (2+2=4). However in this example "a" could also be "a" squared (2 squared=4).

If "a" is any number (other than 2) then a+a = 2a

Hope this helps.

Interestingly enough, 2 is the only number that would work both ways. Not even 1 would work.

I guess that gives 2 magical math properties.:lol:

It's :

a.a = a2

a+a = 2a

and a/a=1
and if a is a constant, the lim a as a---> infinity is a!
and the integral of...sorry...I'm done.

In what case does a+a=3a? (there is an answer...easy one!)

If a=0, then a+a=3a, since 3 x 0 = 0.
