Why is Square 1 negative?

“I” squared is the same thing as the square root of negative 1 times the square root of negative one. Since we know that square rooting and squaring are opposites, the two will cancel each other out, leaving you with negative 1.

Is a negative squared still negative?

“This is because to square a number just means to multiply it by itself. For example, (−2) squared is (−2)(−2)=4. Note that this is positive because when you multiply two negative numbers you get a positive result.” – This, of course, is the exact opposite of what was asked, but it’s the given response.


Why does my calculator say a negative squared is negative?

This is because the ² operation binds more tightly than negation, as others have said. To calculate the square of -5, you would need to enter “(-5)²”. But if with a traditional calculator you input the number -5 in the display and then press the x² key, you should get the correct answer of 25.

Why is negative 2 squared negative?

The phrase “a negative number squared” is, by the most common standard English grammar, interpreted as the square of a negative number (because the word order makes us think first of a negative number and then of the squaring operation) – which produces a positive result (consistent with what happens with your use of …

What is a negative times a negative?

From this, we can show that ab and –ab have opposite signs and therefore that a positive times a negative is a negative. Using the fact multiplication is commutative, a negative times a positive is also negative….Corrollary 3.


(−a) × (−b) = (a × (−1)) × (−b)(Corrolary 3)
(−a) × (−b) = a × b(Corrolary 1)

When a square root is negative?

Negative numbers don’t have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can’t be written as the quotient of two integers.

What is a negative times a positive?

Rule 2: A negative number times a positive number equals a negative number. When you multiply a negative number to a positive number, your answer is a negative number. It doesn’t matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.


Why do 2 negatives multiplied make a positive?

Each number has an “additive inverse” associated to it (a sort of “opposite” number), which when added to the original number gives zero. The fact that the product of two negatives is a positive is therefore related to the fact that the inverse of the inverse of a positive number is that positive number back again.

What happens when you add two negative numbers?

When you have two negative signs, one turns over, and they add together to make a positive. If you have a positive and a negative, there is one dash left over, and the answer is negative.

What is the rule for subtracting negative numbers?

Subtracting a negative number is the same as adding a positive number — that is, go up on the number line. This rule works regardless of whether you start with a positive number or a negative number.

What is the rule for adding and subtracting positive and negative numbers?

When adding positive numbers, count to the right. When subtracting positive numbers, count to the left. When subtracting negative numbers, count to the right.

When you add two negative integers do you always get?

What are the rules for negative and positive numbers?

The Rules:

RuleExample
+(+)Two like signs become a positive sign3+(+2) = 3 + 2 = 5
−(−)6−(−3) = 6 + 3 = 9
+(−)Two unlike signs become a negative sign7+(−2) = 7 − 2 = 5
−(+)8−(+2) = 8 − 2 = 6

What is the rule for minus?

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, – (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 – –4.

What is the formula for negative numbers?

Negative numbers can be thought of as resulting from the subtraction of a larger number from a smaller. For example, negative three is the result of subtracting three from zero: 0 − 3 = −3.

What is the rule for multiplying negative numbers?

You also have to pay attention to the signs when you multiply and divide. There are two simple rules to remember: When you multiply a negative number by a positive number then the product is always negative. When you multiply two negative numbers or two positive numbers then the product is always positive.

What do you get when you divide a negative by a negative?

Rule 3: a negative number divided by a negative number equals a positive number. Two negatives make a positive, so a negative number divided by a negative number equals a positive number. For example, -8 / -2 = 4.

What is the quotient of 0 and a negative number?

How do you add two negative numbers?

Note: Adding two negative numbers together? Just add the absolute value of each number together, put a negative sign in front, and you have your answer!

Why is minus minus a plus?

That is, multiplying by a negative number means that we flip from one side of zero to the other. So, of course if we start from the left of zero (a negative number) and multiply by a negative, we end up on the right of zero (a positive number)!

What is the quotient negative 50 and negative 10?

Step-by-step explanation: The answer would be 5 since negative divided by negative will give us positive.

What is the quotient of 0 divided by?

if zero is to be divided by any number, that means literally 0 apples are to be shared among the given number of people. That means items are there but there no people to share with, which is not a sensible situation. Therefore, 1/0 is not defined. Hence, 0 divided by any divisor gives 0 as the quotient.
