- MULTIPLICATION.
- EX.—25 × 70 = 1750.
- EX.—3·6 × 25 = 90.
- EX.—0·025 × 0·7 = 0·0175.

- EX.—33·6 × 236 = 7930.
- EX.—17,300 × 3780 = 65,400,000.
- By factorising with powers of 10
- EX.—79 × 91 = 7189.
- EX.—42 × 71 × 1·5 × 0·32 × 121 = 173,200.
- DIVISION.
- EX.—225 ÷ 18 = 12·5.
- EX.—0·000221 ÷ 0·017 = 0·013.
- As in multiplication, so in division, we have a
- EX.—3·95 ÷ 5340 = 0·00074.
- EX.—0·00000285 ÷ 0·000197 = 0·01446.
- CONTINUED DIVISION, if we can so call such an expression as
- THE USE OF THE UPPER SCALES FOR MULTIPLICATION AND DIVISION.
- RECIPROCALS.
- EX.—(1)/(339) = 0·00295.
- EX.—(1)/(0·0000156) = 64,100.
- CONTINUED MULTIPLICATION AND DIVISION.
- EX.—(43·5 × 29·4 × 51 × 32)/(27 × 3·83 × 10·5 × 1·31) = 1468.
- MULTIPLICATION AND DIVISION WITH THE SLIDE INVERTED.
- PROPORTION.
- GENERAL HINTS ON THE ELEMENTARY USES OF THE SLIDE RULE.
- SQUARES AND SQUARE ROOTS.
