5th Step.

396. 5th Step. To proceed with the second Example.

Place the different Expansions now found, above each other, Units, Tens, &c. under Units, Tens, &c. preparatory to Addition, thus;

For the Expansion with 4°, .6 on 24, .178:

1st. with 4°, on 24, .0097
2d. with .6 on 24, .00144
3d. with 4°, on .178 .0000712
4th. with .6 on .178 .00001068
