How you do it is 2 + 1 equals 3 and 6+0 equals 6 so put them together and makes 36 and you have worked it out!
N/6 -3 = 10 N/6 = 13 ( add 3 to each side)N = 78 (Multiply each side by 6)
Addition in decimals is commutative; that is, it doesn't matter what order you add the numbers, they will give the same result. So 3 + 6 = 6 + 3 = 9.
It depends on which is further from zero. If it is on the negative side, it will be negative otherwise it is positive. -4 + 6 = 2 -8 + 5 = -3 ___________________ It depends on which of the two numbers is larger. If you add -3 and 6, you get 3 as your answer. But if you add -6 and 3, you get -3 as your answer. To solve, you always subtract the (chronologically) larger number from the smaller one, and the final answer is either positive or negative based on which of the original numbers was larger. To reiterate, -3 plus 6 equals 3, and the answer is a positive number because the higher number in the original equation (6) was as well.
24 plus 61 plus 3 equals 88
