2-2 Basic Calculations

This section explains how to perform basic mathematical operations in the Main application.

Arithmetic Calculations and Parentheses Calculations

•You can perform arithmetic calculations by inputting expressions as they are written. All of the example calculations shown below are performed using the 9 soft keyboard, unless noted otherwise.

•To input a negative value, tap - or -before entering the value.

•The order of operations is followed when a calculation consists of mixed arithmetic operations (multiplication and division are given priority over addition and subtraction).

•The example calculations are all performed using the Decimal mode. Using the Standard mode causes results to be displayed as fractions. For details about the Decimal mode and Standard mode, see “Status Bar Mode Indicators” on page 2-1-4.

23 + 4.5 – 53 = –25.5

cd+e.f-fdw

 

 

 

 

56 ⋅ (–12) ⎟ (–2.5) = 268.8

fg*(-bc)/(-c.f)w

 

 

 

 

(2 + 3) ⋅ 102 = 500

(c+d)Ecw

1 + 2 – 3 ⋅ 4 ⎟ 5 + 6 = 6.6

b+c-d*e/f+gw

 

 

 

 

100 – (2 + 3) ⋅ 4 = 80

baa-(c+d)*ew

 

 

 

 

2 + 3 ⋅ (4 + 5) = 29

c+d*(e+f)w

 

 

 

 

(7 – 2) ⋅ (8 + 5) = 65

(h-c)*(i+f)w

= 0.3

g/(e*f)w or

 

 

) Ngce*fw

4 ⋅ 5

 

 

 

 

(1 + 2i) + (2 + 3i) = 3 + 5i

(b+cP)+(c+dP)w

 

 

 

 

(2 + i) ⋅ (2 – i ) = 5

(c+P)*(c-P)w

 

 

 

 

Tip

•For details about the calculations and result displays produced in each mode, see “Calculation Modes” on page 2-2-5.

•To toggle a result between decimal and fractional format, tap ubefore pressing E.
