RULE 1: The quotient of a positive integer and a negative integer is negative. RULE 2: The quotient of two positive integers is positive. RULE 3: The quotient of two negative integers is positive. If the signs are different the answer is negative.
Addition and Subtraction
Two 'pluses' make a plus, two 'minuses' make a plus. A plus and a minus make a minus.
When the signs of the two numbers are the same, the answer will be positive. When the signs of the two numbers are different, the answer will be negative.
ADDITION/ SUBTRACTION:
):( Positive number plus a positive number, add the two numbers, and it equals a positive number.
When multiplying (or dividing) two numbers with the same signs, the resulting answer is positive. If one is positive and the other negative, the answer will be negative. When more integers are involved work the calculations from left to right.
If both numbers are positive, the result is positive. If both numbers are negative, the result is positive. (Basically, the two negative values cancel each other out). If one number is positive and the other is negative, the result is negative.
When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. Since there is one positive and one negative number, the product is negative 12. Now we have two negative numbers, so the result is positive.
If you've got two positive integers, you subtract the smaller number from the larger one. The result will always be a positive integer: 5 – 3 = 2.
Each person has two Rh factors in their genetics, one from each parent. The only way for someone to have a negative blood type is for both parents to have at least one negative factor. For example, if someone's Rh factors are both positive, it is not possible for his or her child to have a negative blood type.
Q: Can two HIV-positive parents have an HIV-negative child? Yes, they can. Although HIV can pass from a woman with HIV to her child during pregnancy, at the time of birth, or when breast-feeding the infant, medical treatment of both the mother and her infant can minimize the chances of that happening.
The number zero is neither positive nor negative. Positive and negative numbers are sometimes called signed numbers. a. Positive numbers can be written with or without a plus sign.
Rule 1: A positive number times a positive number equals a positive number.
Multiples of 2, like …–8, –6, –4, –2, 0, 2, 4, 6, 8, 10, 12…, are all even, 2 × any integer. Generally: The multiples of an integer are all the numbers that can be made by multiplying that integer by any integer.
If you're multiplying or dividing two numbers that are either both positive or both negative, your result will be positive. If you're multiplying or dividing a positive number and a negative number, your result will be negative.
Robert Lowth stated in his grammar textbook A Short Introduction to English Grammar (1762) that "two negatives in English destroy one another, or are equivalent to an affirmative".
The Law of Sines is the relationship between the sides and angles of non-right (oblique) triangles . Simply, it states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all sides and angles in a given triangle.
Recognize the rules of negative numbers: if two negative numbers are multiplied, the result is positive. However if three negative numbers are multiplied, the result is negative.
That's a magic ratio—five to one. Experts say that when we can greet one negative thought, experience, or sentiment with five positive ones, we can offset our negativity bias.
RULE 1: The product of a positive integer and a negative integer is negative. RULE 2: The product of two positive integers is positive. RULE 3: The product of two negative integers is positive. RULE 1: The quotient of a positive integer and a negative integer is negative.
The negatives cancel out
When you multiply two negative numbers together, though, the first one flips the sign from positive to negative, and the second one flips it back. In other words, negative numbers cancel each other out: when you multiply a negative number by a negative number, you get a positive number.
English grammar is unlike math: two negatives do not make a positive. The best scientific writing is clear, direct, and simple. Do not use two or more negatives in the same sentence or clause, because the two negatives do not cancel each other out but only add confusion to the text.
When you multiply a negative by a negative you get a positive, because the two negative signs are cancelled out.
