Quipeace has updated his “handwriting” calculator for Nintendo DS. Other than other calculators you write the mats onto the screen. The calculators recognizes * : + and -.


Another minor update:

Parenthesis are now supported 2*(4-2) = 4).
NOTE: “1” has to be written like you see it on your screen right now, a simple down-going line will result in a left parenthesis. You will be able to change this in the next release.

Valid input now turns green, and invalid backspaces will no longer erase pixels other than the black line itself.
