What is 50000÷50000×600×700 what does that equal it been 2hours and I can't get it

Let's start by going left to right:

50000/50000 * 600 * 700.

50000/50000 cancels each other out so it's 1.

1 * 600 * 700.

600 * 700 = 420000

1 * 420000 = 420000

b

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
