Vitamins are classified as either fat soluble (vitamins A, D, E and K) or water soluble (vitamins B and C). This difference between the two groups is very important. It determines how each vitamin acts within the body.
Rule 3: Subtracting a negative number from a negative numberâwhen you see the subtraction (minus) sign followed by a negative sign, turn the two signs into a plus sign. Thus, instead of subtracting a negative, you are adding a positive.So, â -5 becomes +5, and continue normally with the addition.ou can also think about these problems as addition problemsâyou add the numbers together (5 + 3 = 8) and then, since both numbers have a minus sign in front of them, you would add a negative sign in front of your answer, like this: -8.
-5 ___ 3. You would answer less than (<) because= negative= numbers= are= always= less= than= positive= numbers= (this= is= because= negative= numbers= are= less= than= zero,= and= all= positive= numbers= are= greater= than= zero).=>.
