CALCULATOR AND COMPUTER-READABLE MEDIUM
First Claim
1. A calculator comprising:
- a display unit having a touch panel;
a recognition unit configured to;
(i) recognize a numerical expression which is handwritten on the touch panel;
(ii) convert the handwritten numerical expression in a text format; and
(iii) display the text-converted numerical expression on the display unit; and
an erasing unit configured to;
if a part of the text-converted numerical expression is erroneously recognized and the erroneously-recognized part is specified,(i) erase the erroneously-recognized part and a part of the handwritten numerical expression corresponding to the erroneously recognized part,wherein if information is handwritten again in the erased part of the handwritten numerical expression, the recognition unit recognizes the handwritten information again, and then the erroneously-recognized part of the text-converted numerical expression is corrected.

Abstract
A calculator is provided. The calculator includes: a display unit having a touch panel; a recognition unit configured to: (i) recognize a numerical expression which is handwritten on the touch panel; (ii) convert the handwritten numerical expression in a text format; and (iii) display the text-converted numerical expression on the display unit; and an erasing unit configured to: if a part of the text-converted numerical expression is erroneously recognized and the erroneously-recognized part is specified, (i) erase the erroneously-recognized part and a part of the handwritten numerical expression corresponding to the erroneously recognized part. If information is handwritten again in the erased part of the handwritten numerical expression, the recognition unit recognizes the handwritten information again, and then the erroneously-recognized part of the text-converted numerical expression is corrected.
