## What is minus minus equal to?

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.

## Why is minus a negative positive?

Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.

## Why negative and negative is positive?

Using the fact multiplication is commutative, a negative times a positive is also negative. Similarly, we can prove that a negative times a negative is a positive. Since we know that −ab is negative, and the sum of these two terms is 0, therefore (−a) × (−b) is positive.

## Can you subtract a number from zero?

Subtraction. Like addition, if you subtract 0 from any number, you get the same sum. For example, 12-0 = 12. If you’re subtracting, you may need to use borrowing to solve the problem.

## Does a minus times a minus equal a positive?

Two negatives make a positive, so a negative number times a negative number makes a positive number. If you look at it on the number line, walking backwards while facing in the negative direction, you move in the positive direction. For example. -2 x -4 are both negative, so we know the answer is going to be positive.

## Why negative minus negative equals positive?

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. So we’re changing the two negative signs into a positive, so the equation now becomes -2 + 4.

## What is negative plus negative?

While it’s true that a negative times a negative is a positive, a negative plus a negative is actually a negative.

## What happens when you multiply a negative by a negative?

The negatives cancel out In other words, negative numbers cancel each other out: when you multiply a negative number by a negative number, you get a positive number.

## Why is a negative squared still 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 happens when you multiply a negative and a positive?

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. 3 times 4 equals 12. When you divide a negative number by a positive number then the quotient is negative.

## What happens when you multiply 3 negative numbers?

## Why is negative 1 squared negative?

The calculator said -1 because of the way calculators handle inputs. When a calculator sees it breaks it down in an odd way. Instead of how a person would interpret it, as squaring negative one, a calculator interprets it as taking 1 squared and returning its negative. This returns negative one.

## What is the power of a negative number?

A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16.

## What does 10 to the minus 3 mean?

10-3 = = 0.001. Step 3: Using a shortcut, we find that the exponent is -3. We write a decimal point followed by two 1lessthan3 zeros and a 1. So 10-3 = 0.001.

## What is a negative power of 10?
