UNIT INDEX
1: MULTIPLICATION
To divide with the Slide rule Bezel, also
use the unit index (10 with triangle).
Place the dividend (the quantity to be
divided by another number) on the outer
scale opposite the divisor (quantity by
which another is divided) on the inner
scale. Opposite the unit index (numeral
"10" on inner scale), read answer on
outer scale.
Example:
Divide 120 by 4. Place 120 on outer
scale opposite 4 on the inner scale. Read
answer, 30, on outer scale opposite unit
index (10 with triangle on inner scale).

UNIT INDEX
To multiply with the Slide Rule Bezel,
use the unit index (number "10" with
triangle in the inner scale). Always set
the multiplier (the number by which
another is multiplied) opposite the unit
index on the inner scale and read the
answer on the outer scale opposite the
multiplicand number (number to be
multiplied by another) appearing on the
inner scale.
Example:
To multiply 7 x 12, set 12 (the multiplier)
on outer scale opposite unit index ("10")
on the inner scale. Opposite 7 (the
multiplicand) on the inner scale, read the
answer 84 on the Bezel.
