<u>Answer:</u>
The correct answer option for this is: False.
<u>Step-by-step explanation:</u>
We are given the following statement which we are to determine whether its true or false:
<em>In order to form a negation, just add "not" to a statement or take "not" out of a statement if it already exists.</em>
To form a negation, we add the word 'not' to a statement - this part of the given sentence is true.
While 'or take "not" out of a statement if it already exists' is false which makes the whole sentence false.
In this problem, we are asked to give an expression that can be used to mentally multiply 6 and 198. In order not to go through the rigorous multiplication, we can estimate 198 to 200, that is 6 *200 equal to 1200. Since there is a 2*6 excess or 12 then we subtract: 1200 -12 equal to 1188.
