Multiplication and Division of Signed Mumbers: Determine the resulting sign from the exercise

When there is no minus or plus sign before the numbers, we usually assume that these are positive numbers,

meaning, the expression equals to

(+1/4)*(+1/2)=

The dot in the middle represents multiplication.

So the question in other words is - what happens when we multiply two positive numbers together?

We know that plus times plus equals plus,

therefore the answer is "positive".

To solve the exercise you need to remember an important rule: Multiplying a positive number by a negative number results in a negative number.

$(−)×(+)=(−)$
Therefore, if we multiply negative 2 by 2 the result will be negative 4.

That is, the result is negative.

$+2\times-2=-4$

It's important to remember: when we multiply a negative by a negative, the result is positive!

You can use this guide:

Let's recall the law:

$(-x)\times(-x)=+x$

Therefore, the sign of the exercise result will be positive:

$-2\times-\frac{1}{2}=+1$

Let's remember the rule:

$(-x)\times(-x)=+x$

Therefore, the sign of the exercise result will be positive:

$-3\times-4=+12$

Let's remember the rule:

$(+x)\times(-x)=-x$

Therefore, the sign of the exercise result will be negative:

$-4\times+12=-48$

Let's remember the rule:

$(+x)\times(+x)=+x$

Therefore, the sign of the exercise result will be positive:

$+6\times+3=+18$

Remember the law:

$(+x)\times(-x)=-x$

For the sum of the angles of a triangle is always:

$-6\times+5=-30$

Let's remember the rule:

$(+x)\times(-x)=-x$

Therefore, the sign of the exercise result will be negative:

$+5\times-\frac{1}{2}=-2\frac{1}{2}$

We will only look at whether the number is negative or positive.

In other words, the division exercise looks like this:

$+:+=$

Since we are dividing a positive number by a positive number, our result will necessarily be positive.

We will only look at whether the number is negative or positive.

In other words, the division exercise looks like this:

$+:+=$

Since we are dividing a positive number by a positive number, the result will necessarily be a positive number.

Let's remember the rule that anything we divide by zero will give us a result of zero:

$\frac{0}{x}=0$

$0:x=0$$$

Therefore, the answer is zero.

We will only look at whether the number is negative or positive.

In other words, the division exercise looks like this:

$-:+=$

Since we are dividing a negative number by a positive number, the result will necessarily be a negative number.

We will only look at whether the number is negative or positive.

In other words, the division exercise looks like this:

$+:-:+=$

If we solve the exercise from left to right, we will first divide plus by minus:

$+:-=-$

Now the remaining exercise is:

$-:+=-$

Therefore, the sign of the exercise result will be negative.

We will only look at whether the number is negative or positive.

In other words, the division exercise looks like this:

$-:-=$

Since we are dividing a negative number by a negative number, the result will necessarily be a positive number.

Let's see if the number is negative or positive.

As you can see, in the expression the numerator is negative and the denominator is positive.

That is, the division exercise will look like this:

$\frac{-}{+}:-=$

The result of the expression will be a negative number, since we are dividing a negative number by a positive number.

Therefore, the exercise that will be obtained will look like this:

$-:-=+$

Therefore, the sign of the result of the exercise will be negative.

We will only look at whether the number is negative or positive.

In other words, the division exercise looks like this:

$\frac{-}{-}:-=$

If we solve the exercise from left to right, we will first divide the numerator of the negative fraction by the denominator of the negative fraction.

Therefore, the resulting fraction will be positive:

$\frac{-}{-}=+$

Now the remaining exercise will look like this:

$+:-=-$

Therefore, the sign of the exercise result will be negative.

We will look only at whether the fraction is negative or positive.

In other words, the multiplication exercise looks like this:

$-\times+\times+=$

If we solve the exercise from left to right, we'll first multiply minus by plus:

$-\times+=-$

Now the remaining exercise is:

$-\times+=-$

Therefore, the sign of the exercise result will be negative.

We will only look at whether the number is negative or positive.

In other words, the exercise looks like this:

$-\times\frac{+}{-}:-=$

If we solve the exercise from left to right, we'll first multiply the fraction:

$-\times\frac{+}{-}=$

Since the numerator of the fraction is positive and divides by the negative denominator, the resulting fraction will be negative.

Now the remaining exercise is:

$-\times-:-=$

If we multiply minus by minus, we'll get a positive number:

$-\times-=+$

Now the resulting exercise is:

$+:-=-$

Therefore, the sign of the exercise result will be negative.

In this question, we only need to work out whether the resulting value is negative or positive.

In other words, the division exercise can be considered as follows:

$\frac{-}{-}:+=$

If we solve the exercise from left to right, we first divide the numerator of the negative fraction by the denominator of the negative fraction:

$\frac{-}{-}=+$

This leaves us with:

$+:+=+$

Therefore, the result of the exercise will be positive.
