400 - 190 = 210
400 + 190 = 590
598
10%-190=19-190=-171 But 190-10%=190-19=171
It is 47.5%
560 - 370 = 190
400 - 30 = 370
400 - 398 = 2
1382 - 400 = 982
400 - 125 = 275
The question above would be written as 950--400 and when you have a minus and a minus together they make a positive, so the actual question is 950+400 which equals 1350.
841 minus 441 is 400.
1000 + 400 - 300 = 1100
