can anyone help me with level 2 and 3 of intern base
im stuck on

maths at light speed, off balance and the final countdown

for traffic jam if you look at the forum you'll see <li data-sd="my-chat" data-id="312324494" class="disabled">Forum</li> look at how the other url sites on the page look and youul'll see for Cycling Maps you get https://my-routes.trafficdisruptors.com/312324494 so like wise you'll replace my-routes with my-chat then 312324494 with 312324494

Michael could elaborate more with doing the calculations for maths at light speed I don’t quite understand

for Hextraordinary you get the code 0xB105F00D 0xAAA8400A its a XORCalculator that translates to 1badb007 if you read the email it say the code should start with the same 0x prefix so 0x1badb007.

for Math at light speed before you do anything you well see <form class="form" action="/flashfast/answer" id="calc-form"> in the html code click spin then you see <form class="form" action id="calc-form"> so change the action back to action="/flashfast/answer" then solve the calculator iv the blue dot is on - subtract the numbers like wise with + you'll just add them but that number in the box then you'll see the flag

I can't get any numbers to show up on the calculator. How would I go about doing that?

Does anyone have the answer to Off Balance I have completed all of the other ones?
