Subtract by place
For 675 − 243, subtract 200 to reach 475, subtract 40 to reach 435, then subtract 3 to reach 432. Keeping the parts visible helps you check what remains.
Cross a hundred in two steps
For 504 − 126, subtract 4 to reach 500, then subtract the remaining 122 to reach 378. Check backwards: 378 + 126 = 504. The answer stays non-negative in this practice round.
