$\ 10a4b$ $\underline{-85c4}$ $\ \ \ d7\underset\uparrow 10\ \leftarrow b-4=0\ so\ b=4$ $\ \ \ \ \ \ \ 4-c=1,so\ c=3$ $\ 10a44$ $\underline{-8534}$ $\ \ \ d\underset\uparrow 710$ $\ \ \ \ \ \ a-5=7.$ Since $7\gt5$ borrowing was done. $\ \ \ \ \ \ a+10-5=7,\ so\ a=2$ $\ \ \ \overset9/\!\!\!\!\!10244$ $\underline{-8534}$ $\ \ \ \underset\uparrow d710$ $\ \ \ 9-8=d,\ so\ d=1$
