A. 426
B. 300
C. 306
D. 200

Answer 1

B. 300

Answer 2

This is one you might easily check on a calculator. If you're trying to do it quickly, though, look for terms that, when added together, make the whole calculation easier. No need to just add it all up at once.

Like 263-63 = 200. 83+17 = 100. 100+200 = 300.
