Maths subtraction maths problem

The is my maths problem I have to work out. This question is asking you what is 381 - 127. This is how I work it out. 
Firstly 381 - 100 = 281
Secondly 281 - 20 = 261
Thirdly 261 - 1 = 260
260 - 6 = 254
The answer is 254. On the third step the reason why I subtracted 1 instead of 7 is because it's more easier to subtract from a tidy number.
