2-1-1 Basic Calculations 2-1 Basic Calculations k Arithmetic Calculations • Enter arithmetic calculations as they are written, from left to right. • Use the - key to input the minus sign before a negative value. • Calculations are performed internally with a 15-digit mantissa. The result is rounded to a 10-digit mantissa before it is displayed. • For mixed arithmetic calculations, multiplication and division are given priority over addition and subtraction. Example 23 + 4.5 - 53 = -25.5 Operation 23+4.5-53w 56 × (-12) ÷ (-2.5) = 268.8 56*-12/-2.5w (2 + 3) × 102 = 500 (2+3)*1E2w*1 1 + 2 - 3 × 4 ÷ 5 + 6 = 6.6 1+2-3*4/5+6w 100 - (2 + 3) × 4 = 80 100-(2+3)*4w 2 + 3 × (4 + 5) = 29 2+3*(4+5w*2 (7 - 2) × (8 + 5) = 65 6 4×5 = 0.3 3 10 (7-2)(8+5)w*3 6 /(4*5)w*4 $6c4*5w (1 + 2i) + (2 + 3i) = 3 + 5i (b+c!a(i))+(c+ d!a(i))w (2 + i) × (2 - i) = 5 (c+!a(i))*(c-!a(i) )w *1(2+3)E2 does not produce the correct result. Be sure to enter this calculation as shown. *2Final closed parentheses (immediately before operation of the w key) may be omitted, no matter how many are required. *3A multiplication sign immediately before an open parenthesis may be omitted. *4This is identical to 6 / 4 / 5 w. 20050401
