2. Rotate crown until the large arrow on the inner scale is aligned with the
number «60» on the outer scale. Notice that all the numbers in the inner
and outer scale match up.
3. Decimal points. Depending on the context of your problem, you will decide
whether to read the number “10” on the inner scale as 1, 10, 100 or 1,000.
The markers between numbers indicate the calibration. (e.g., the calibra-
tion between 10 and 11 are each 0.1 so, 2 calibrations above the 10 will
read at 10.2. The calibration between 15 and 16 are each 0.2 so 2 calibra-
tions above the 15 will read as 15.4)
Multiplication
1. Set the large 10 with the arrow on the inner scale over the number you want
to multiply on the outer scale. (e.g., for 32 x 7 = 224, set the (10/arrow)
number opposite the 32 on the outer scale.)
2. Read the result on the outer sca
le opposite the number you are multiplying
by on the inner scale. (e.g., for 32 x 7, read the number on the outer scale
opposite 7 on the inner scale).
