for calculations in primary

Calculator required for some math workbook exercises for my daughter in CE2 (already? ... I thought we were still learning to calculate head, I regret but the program is done),
if not for the calculator in question, practical side: big buttons, it is very easy to use, a memory button, flip to protect, flashy pink color that delights the little girls.
It corresponds at any point in description. and for 5 euros is well suited priori primary classes.
