Using the accepted convention, MMMCMXCIX (3999) is the largest numeral. The accepted convention does not permit any symbol to repeat more than three times in succession.
A Roman numeral can be considered invalid due to several reasons. These include using a repetition of the same numeral more than three times in succession (e.g., IIII instead of IV), writing a numeral in a descending order (e.g., XCX instead of C), or using a numeral that is not part of the standard Roman numeral system (e.g., A instead of I).
(44-4)/4
4*4+4=20
To find 3 times 2.7 using a quick picture, you can represent 3 as three groups of equal parts and 2.7 as a decimal number. Draw three equal groups and divide each group into tenths to represent 2.7. Count the total number of tenths in the three groups, which equals 8.1. Therefore, 3 times 2.7 is equal to 8.1.

Using Middle Age Roman numeral notation, an overline multiplies the value by 1000. Thus 84,000 is 84 times 1000, which is notated as follows: ______ LXXXIV
Using multiplication 40 times 45 = 1800
