For the sake of the example, the above calculation will be performed with the value
33 mistakenly entered as 34.
34 * 5 + 16
.
.
34*5+16

Practice the following examples to become familiar with the fundamental calculation
procedure.
EXAMPLE 1:
9 + 7.8 6 – 3.5 x 2 = 3.3
OPERATION:
9 + 7.8 / 6 - 3.5 * 2
.
.
9+7.8/6-3.5*2
3.3
EXAMPLE 2:
56 x (-12) (-2.5) = 268.8
OPERATION
56 * - 12 / - 2.5
.
.
56*-12/-2.5
268.8
Negative values are entered by pressing the - key before entering the value.
