Where is the math button on the casio fx-9750G11

It is a calculator and prqactically every button is a MATH button. It depends on what MATH you intend to do. Put the calculator in Run/Mat screen then press the OPTN key. You will see several tabs. Press the function key under a TAB and explore what is offered. Go through all the keys (F6 also) and see what the new tabs do.
In general it is most helpful to read the manual that shipped with the calculator.
