![OB Camp: Challenge 2 [READ DESCRIPTION!]](https://cdn2.scratch.mit.edu/get_image/project/304853216_480x360.png)
Press space for the next slide. Explanations for the answers: 1: 2 plus 2 is obviously 4! No explanation needed. 2: 50 percent of 80 is just half of 80, making the answer 40. 3: One more than 55 is 56. 4: 331 minus 45 is by far the hardest, 1st, you take away the 5 in 45, leaving the number at 326 minus 40 from that is 286. 5: 40 percent of 100 is 40. I can't explain it, it's too easy.
Thanks to hani2018 for the camp.
