My fx-991ES PLUS calculator won't show results in scientific notation for certain operations
Namely, operations with scientific notation in them. I've already tried formatting it differently ((1.99×10^2)÷(8.2×10^-5)) and doing different operations (adding, subtracting) but it still won't give me results in scientific notation. I configured the calculator so it would always give me the answers in either scientific notation or fractions and it does show when I do other, simpler operations, like you can see in the second image, so I know it's not a problem with how it's configured. I've already tried pressing the S<=>D button but that also doesn't work. Does anyone have any idea as to what I should do?
