Should be equal to. sorry if its incorrect, but that's what i would go with.
Counting numbers is like the numbers 1,2,3,4,5 and so on they were numbers you were probably taught to count to like to count through 1-10 or whatever. Counting numbers mean to count since they do have the word counting in them.
Whole number just means a number with no fraction or intger also 1 - infinity
If a coat is regularly $125, and they mark it down to $75, we could figure out how much money was taken off by subtracting $75, from $125
$125 - $75 = $50
So the coats price was cut by $50.
Hope it helps
