The arithmetic operators used in mathematical expressions are as follows:

a$.$ adotion uses &$,$ suberaction uses $$,$ multialication uses #$,$ division uses $/,$ and modula division uses

b$.$ adarion uses e$,$ subtraction uses $-$ multplication uses $*.$ division uses $\frac{\frac{?}{?}}{?}$ and modulo division uses

c$.$ addtion uses $+,$ subtraction uses $-$ multipication uses $*$ division uses $\frac{?}{?},$ and modulo division uses $\%$

d$.$ addition uses & subtraction uses $-$ multiplication uses e$,$ division uses $\frac{?}{?},$ and modulo divsion uses
