The result is rounded to a10-digit mantissa before it is displayed.• For mixed arithmetic calculations, multiplication and division are given priority overaddition and subtraction.Example Operation23 + 4.5 – 53 = –25.5 23+4.5-53w56 × (–12) ÷ (–2.5) = 268.8 56*-12/-2.5w(2 + 3) × 102 = 500 (2+3)*1E2w*11 + 2 – 3 × 4 ÷ 5 + 6 = 6.6 1+2-3*4/5+6w100 – (2 + 3) × 4 = 80 100-(2+3)*4w2 + 3 × (4 + 5) = 29 2+3*(4+5w*2(7 – 2) × (8 + 5) = 65 (7-2)(8+5)w* 36 = 0.3 6 /(4*5)w* 44 × 5(1 + 2 i) + (2 + 3 i) = 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 correctresult. Be sure to enter this calculation as shown.* 2 Final closed parentheses (immediately beforeoperation of the w key) may be omitted, nomatter how many are required.*3 A multiplication sign immediately before an openparenthesis may be omitted.*4 This is identical to 6 / 4 / 5 w.
