Calculation:
(100 - 990) x 100
= (-890) x 100
= -89000
= -9900 x (-1)
= 9900
Explanation:
To solve the given expression, we need to follow the order of operations, which is also known as BODMAS or PEMDAS. In this case, we have only multiplication and subtraction, so we can perform them from left to right.
(100 - 990) x 100
= (-890) x 100 [Subtract 990 from 100, which gives -890]
= -89000 [Multiply -890 by 100]
= -9900 x (-1) [Express -89000 as a product of -9900 and -1]
= 9900 [Since a negative number multiplied by a negative number gives a positive number, the answer is positive]
Therefore, the correct answer is option 'C' (9900).
(100 - 990) x 100
= (-890) x 100
= -89000
= -9900 x (-1)
= 9900

(100-99^0)*100
= (100-1)*100. (as we know a to the power zero equals to 1 so 99 to the power zero equals to 1)
=(100-1)*100=99* 100=9900.
= (100-1)*100. (as we know a to the power zero equals to 1 so 99 to the power zero equals to 1)
=(100-1)*100=99* 100=9900.
