It's easy

Good for beginners

This one was a tricky one had to find values but i also like maths 2_5

strings + wolfram alpha

LMAO so true

thanks

bruh i just had a maths test and i come here to do something fun but it's still algebra, all algebra, more algebra, everything is algebra, everybody you love is algebra, everything you love is algebra, algebra

If you don't like math stay away from the Crypto challenges :-)

I found the flag and i know it's right but when I put it into the bar it says it's incorrect. What do I do?

Reply with a protected comment with your flag and I will check it, or maybe google how to solve this one

replace x and y values

This was really fun! I like the combination of math and cs, but I would put there a little bit harder math problem.
