The Rules of Using Positive and Negative Integers

Whole numbers, which are figures that do not have fractions or decimals, are also called integers. They can have one of two values: positive or negative. Positive integers  have values greater than zero.Negative integers have values less than zero.  Zero is neither positive nor negative. The rules of how to work with positive and negative numbers are important because youll encounter them in daily life, such as in balancing a bank account, calculating weight, or preparing recipes. Tips for Success Like any subject, succeeding in mathematics takes practice and patience. Some people find numbers easier to work with than others do. Here are a few tips for working with positive and negative integers:Context can help you make sense of unfamiliar concepts.  Try and think of a practical application like keeping score when youre practicing.Using a number line showing both sides of zero is very helpful to help develop the understanding of working with positive and negative numbers/integers.Its easier to keep track of the negative numbers if you enclose them in brackets. Addition Whether youre adding positives or negatives, this is the simplest calculation you can do with integers. In both cases, youre simply calculating the sum of the numbers. For example, if youre adding two positive integers, it looks like this: 5 4 9 If youre calculating the sum of two negative integers, it looks like this: (–7) (–2) -9 To get the sum of a negative and a positive number, use the sign of the larger number and subtract. For example: (–7) 4 –36 (–9) –3(–3) 7 45 (–3) 2 The sign will be that of the larger number. Remember that adding a negative number is the same as subtracting a positive one. Subtraction The rules for subtraction are similar to those for addition. If youve got two positive integers, you subtract the smaller number from the larger one. The result will always be a positive integer: 5  Ã¢â‚¬â€œ 3 2 Likewise, if you were to subtract a positive integer from a negative one, the calculation becomes a matter of addition (with the addition of a negative value): (–5)  Ã¢â‚¬â€œ 3 –5 (–3) –8 If youre  subtracting negatives from positives, the two negatives cancel out and it becomes addition: 5  Ã¢â‚¬â€œ (–3) 5 3 8 If youre subtracting a negative from another negative integer, use the sign of the larger number and subtract: (–5)  Ã¢â‚¬â€œ (–3) (–5) 3 –2(–3) – (–5) (–3) 5 2 If you get confused, it often helps to write a positive number in an equation first and then the negative number. This can make it easier to see whether a sign change occurs. Multiplication Multiplying integers is fairly simple if you remember the following rule: If both integers are either positive or negative, the total will always be a positive number. For example: 3 x 2 6(–2) x (–8) 16 However, if you are multiplying a positive integer and a negative one, the result will always be a negative number: (–3) x 4 –123 x (–4) –12 If youre multiplying a larger series of positive and negative numbers, you can add up how many are positive and how many are negative. The final sign will be the one in excess.   Division As with multiplication, the rules for dividing integers follow the same positive/negative guide. Dividing two negatives or two positives yields a positive number: 12 / 3 4(–12) / (–3) 4 Dividing one negative integer and one positive integer results in a negative figure: (–12) / 3 –412 / (–3) –4

Optimism, taking risks, thinking outside the box, going above and beyond, these are characteristics that mold the successful. On a global or national scale the Oak Island Money Pit outside of Nova Scotia may not be a priority to governments, but it concerns me nobody has investigated it further. In 1795 three teenagers from Nova Scotia began to dig on the island, every ten feet they found a wooden plank, after thirty feet the excavation was abandoned. Later at ninety feet a stone with writing was discovered which translated to â€Å"forty feet below, two million pounds lie buried.† After digging further, the hole would fill up with water and nobody knows why. Diggers tried from different directions to reach the so-called treasure of Captain Kidd, but never succeeded. Cranes, and all types of machines have been introduced, but nothing was discovered.

Maybe the idea of a pirates buried treasure is too good to be true, but why not take the risk. The worst that could happen, well assume the latter. Nonetheless the riches acquired if there happens to be a treasure would be astounding, this concerns me that nobody will take the risk. You don’t need to have endless amounts of cash to fund an excavation, simply assemble a team of Goonies. Something has to be done, someone must step up and explore the possibilities, think outside the box. Maybe the concern of the money pit may be low and other situations take priority, but look at the idea and tell me if the hole is half empty or half full. If a nation funds the project and discovers riches, it would be free money and global popularity. Why doesnt somebody think outside the box and find a way to dig past the water, who knows what could be down there. Why should something as far-fetched as the money pit concern me? I like answers, resolution, if I don’t know something I have to figure it out, and if I can’t I will reach in with a death grip and pull until it surfaces. The money pit is a risk, I enjoy taking risks, if you don’t take risks, you won’t get anywhere. In order to succeed you have to think outside the box, this is also a risk. Go out on a limb, and stay there until you succeed, this is my philosophy. This is why the Oak Island money pit concerns me, nobody will take the risk.
