Why does subtracting a negative equal a 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.
What does a negative minus a positive equal?
):( Negative number minus a positive number, adds the numbers, and keeps the negative sign.
How do you explain subtracting integers?
Subtraction of integers can be written as the addition of the opposite number. To subtract two integers, rewrite the subtraction expression as the first number plus the opposite of the second number. Some examples are shown below. To subtract two integers, add the opposite of the second integer to the first integer.
Is 7 positive or negative?
Any number without a minus sign in front of it is considered to be a positive number, meaning a number that’s greater than zero. So while -7 is negative seven, 7 is positive seven, or simply seven.
Why do negatives cancel out?
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.
What happens when you add a negative number to a negative number?
When you are adding a negative number to a negative number, it becomes subtraction, where you start from a negative point on the numbers line and move left.
What does a negative plus a negative equal?
When you are adding a negative number to a negative number, it becomes subtraction, where you start from a negative point on the numbers line and move left. For example, -3 + (-2). This reads “negative three plus negative 2”.
What is the value of-2 minus negative 4?
This would read “negative two minus negative 4”. So we’re changing the two negative signs into a positive, so the equation now becomes -2 + 4. On the number line, it starts at -2. Then we move forward 4 units: +4. class=”green-text”>The answer is -2 – (-4) = 2.
What would negative two times six plus negative six be equal to?
We want whatever this answer to be consistent with the rest of mathematics that we know so we can do the same product experiment. What would negative two times six plus negative six to be equal to. Well, six plus negative six is going to be zero.
What is the difference between Plus and minus in math?
That is, by plus-ing a minus, you’re adding in the other direction. In the same vein, if you subtract a negative (that is, if you minus a minus), you’re subtracting in the other direction; that is, you’ll be subtracting by moving to the right.
What is the rule for subtracting negative numbers?
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.
