Question

The result of which expression will best estimate the actual product of (1899) 06-1()-1-1 0 (-1){})(-101) 19?

a) 1900
b) 2000
c) 1800
d) 1700

Answer 1

To estimate the actual product of the given expression, we need to simplify it step by step. The best estimate is -3,640,000, which rounds to d) 1700.

Step-by-step explanation:

To estimate the actual product of the expression (1899) 06-1()-1-1 0 (-1){})(-101) 19, we need to simplify the expression. Let's break it down step by step:

1. Remove the parentheses: (1899) 06-1-1-1 0 -1 -1 -101 19
2. Multiply any numbers with the same sign: (1899) 06-1-1 0 -1 -1 -101 19
3. Multiply the numbers: 1899 * 06 * (-1) * (-1) * 0 * (-1) * (-1) * (-101) * 19
4. Calculate the result: -3,640,040

The result of the expression is -3,640,040. Since the question asks for the best estimate, we can round this to the nearest thousand, which is -3,640,000. Therefore, the best estimate of the actual product is d) 1700.
