90<->10<%>=81calculates as:90-(10%of90)=81
9010<%>=810calculates as:90x(10%of90)=810
9010<%>=10calculates as:90/(10%of90)=10
10<%>=0calculates as:calculator does not process
For the <+>, <->, , operators, the calculator watch the 10 <%> as 10% that 90 which is same to 9. Calculator C:
90<+>10<%>=90.1calculates as:90+(0.1)=90.1
90<->10<%>=89.9calculates as:90-(0.1)=89.9
9010<%>=9calculates as:90x(0.1)=9
9010<%>=900calculates as:90/(0.1)=900
10<%>=0.1calculates as:10/100 i beg your pardon is same to 0.1
For the <+>, <->, , operators, the calculator sees the 10 <%> together 10/100 which is same to 0.1
