BODMAS would say that addition is before subtraction. There is a main code "DMAS", which prove that: D:Divide M:Multiplication A:Addition S:Subtraction It proves that Addition is before Subtraction. HOPE U LIKE THAT:)


Why are subtraction addition multiplication division called reciprocal or inverse operations?

The inverse operation of addition would be subtraction. The inverse operation of subtraction would be addition. The inverse operation of multiplication is division and the inverse operation of division is multiplication. It is called the inverse operation because you are reversing the equation. If you add, subtract, multiply, or divide the same number on each side of the equation, then the equation would still be true. As long as you are doing the same thing on BOTH side of the equation. The reciprocal is used for dividing fractions. All you have to do for finding the reciprocal of a fraction is flip the fraction. Ex: The reciprocal of 1/4 is 4. The reciprocal of 5/8 is 8/5. You can check by multiplying the two fractions. It will equal to one if you did it right. I hope this helped a little bit.
