Question

What is $7 \times \left( { - 7} \right)$?

Answer 1

Hint: Here, we have to multiply 7 by $ - 7$. So the multiplicand will be 7 and the multiplier will be $ - 7$. Here the minus sign $\left( - \right)$ means that the number is less than 0. The method to multiply 7 by $ - 7$ will be the same as we multiply 7 by 7. The only difference is we will put a minus sign in front of our answer in this case.

Complete step by step solution:
In this question, we have to find $7$ multiplied by $ - 7$.
The number that is to be multiplied is called multiplicand, which is 7 in our question.
And the number that we are multiplying is called a multiplier, which is $ - 7$ in our question.
In simple words, we have to find the number that we will obtain if we add 7 times 7.
You might be wondering about the minus sign $\left( - \right)$ before the multiplier 7.
This minus sign indicates that our multiplier 7 is less than 0. The method to multiply $7$ by $ - 7$ is the same as we multiply $7$ by $ - 7$. The only difference is that we will have to put a minus sign before the answer in this case.
So, if we multiply $7$ by $7$, we get
$7 \times 7 = 49$.
Similarly, if we multiply $7$ by $ - 7$, we get
$7 \times - 7 = - 49$.
Therefore, $7$ multiplied by $ - 7$ is equal to $ - 49$.

Additional Information:
There is a famous rule in mathematics known as BODMAS.
This states that when given an equation or expression, we should first calculate the brackets $\left( {\left( {2 + 1} \right)} \right)$, then any order $\left( {{2^2} = 4} \right)$, then division $\left( {10 \div 2} \right)$, then multiplication $\left( {4 \times 6} \right)$, then addition $\left( {4 + 3} \right)$ and then subtraction $\left( {4 - 2} \right)$.

Note:
> If both multiplicand and multiplier are positive, the answer will be positive.
> If multiplicand is negative and multiplier is positive, the answer will be negative.
> If multiplicand is positive and multiplier is negative, the answer will be negative.
> If multiplicand is negative and multiplier is negative, the answer will be positive.
