Question

what does the @ sign mean in algebra

Answer 1

does not have meaning that I am aware of. Did you see it in a SAT question?

Answer 2

no my algebra teacher put it on a worksheet

Answer 3

post the question, but you might want to ask you teacher. Maybe it is a typo and they meant the number 2

Answer 4

a@b =2a/b and a#b- 2a^2 +3b-5 find the value of 3@(2#4)

Answer 5

what is a# b -
did you mean to write a#b = -2a^2+3b-5

Answer 6

yes sorry

Answer 7

well a is your 3 and b is your 2#3
they are using it as a place holder (for a lack of a better word)
this means a=3

Answer 8

ok Let me work this out for you. In SAT they sometimes use a heart or some type of symbol - means nothing just defines things

Answer 9

ok i get that i just didnt know what to do with the @ sign

Answer 10

thanks for your help

Answer 11

ok here it goes
a#b=\[-2a^2+3b-5\]
2#4 means a is 2 and b is 4 so sub
2#4=\[-2(2)^2+3(4)-5\]=-1

Answer 12

that makes sense

Answer 13

a@b = (2a)/b
3@(2#4)=3@-1 so a is 3 and (2#4) is -1
3@-1=(2*3)/-1=-6

Answer 14

have fun, you will see these on SAT's

Answer 15

ok ill try to :)
