Solve the following: -3 * 12 / 4 * 8 + (4-6)
Solve the question using PEMDAS Rule i.e. Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction Solve Parenthesis (4 - 6 ) = -2 Now we have multiplication and division so look at the equation from left to right which ever comes first. Solve the equation from left to right Multiply - 3 * 12 = -36 Then divide -36 / 4 =9 Multiply -9 * 8 = -72 Now you have - 2 from parenthesis and -72 from rest of equation Now you can subtract -72 + (- 2) = -72 - 4 = -72
Correct the following sentence The people of the Mughal Empire were fighters, although they also created some artistic master pieces.
The subject is people, which is plural. Subject should agree with verb which is also plural. The verbs "were" and "created" should be in the same tense as they happened in the past. Therefore, the correct sentence is: The people of the Mughal Empire were fighters, although they also created some artistic master pieces.
