does the star mean multiply or does it mean something else??
Yes, star means multiplication.
But then 5*1 would just be 5, and that's not correct. Maybe the star stands for something?
The star is just an operation symbol
a * b = 5 * 1
So a = 5 and b = 1
So
5 star 1 =
9a + 2b - ab + 5 =
9(5) + 2(1) - (5)(1) + 5 =
45 + 2 - 5 + 5 =
47
Ohhhhh. Thanks! It makes so much more sense now!
But you mean 47 right?
Yep 47
(I gotta' get some glasses !!)
