Common Core Math Problem: How to Subtract 293 from 568 in Just 10 Steps! (With Picture)!

Imagine a teacher asks you to solve this question: 568-293. Depending on your age you might do one of three things...
...Third, you might use the new common core was to subtract, which is much simpler, with only... 10 steps.
First, you would take the 200 out of the 293, and save the 93 for later. Then you would take 568 and subtract 200 from it. Then you'd take the remaining 368 and you would subtract 60 from it, because you are taught that, for some reason, you cannot simply subtract 90 from 368. 368-60 equals 308. Then you subtract 30 from 308 because, again, for some reason 368-90 doesn't exist. 308-30 equals 278. Then you take the three that is left over from 293-290, because you already subtracted 200, 60, and 30 from 293 to get three, and you minus that 3 from the remaining 278 that you got from subtracting 290 from 568. Still following? Good, because one you minus 3 from 278, you get the answer of 275! Then, you double check your answer by adding up 200 + 60 + 30 + 3 to get 293, which is the number you subtracted from 568. Much, much more complicated than the other two methods and an over-complification of a simple problem. More than that, the way to figure out this problem is literally more than the other two methods combined.
This is an actual common core problem which, hilariously, tries to tell students its a mere three steps: Common Core Math
