What is 190 plus 890 plus 780 plus 690 plus 590 plus 490 plus 390 plus 290 plus 190 plus 90?
190 + 890 + 780 + 690 + 590 + 490 + 390 + 290 + 190 + 90 = (190 + 890) + (780 + 690) + (590 + 490) + (390 + 290) + (190 + 90) = 1080 + 1470 + 1080 + 680 + 280 = 4590 Answer = 4590

What is 100 plus 90 plus 60 plus 80?
The result of the equation - 100 plus 90 plus 60 plus 80, is found as follows; 100 + 90 + 60 + 80 = ( 100 + 90 ) + 60 + 80 = 190 + ( 60 + 80 ) = 190 + 140 = 330 Answer = 330
What is 150 plus 890 plus 790 plus 690 plus 590 plus 490 plus 390 plus 290 plus 190 plus 90?

Add 12 percent tax to 190 dollars?
Just multiply 190 by 1.12 and you will have your answer. This is how I get the "1.12". The final amount will be 190 dollars PLUS twelve percent of 190 dollars. This can be expressed: 190 dollars (1 PLUS 12 percent). 190 ( 1 + .12). The 190 times 1 gives you, not surprisingly, the whole original 190 dollars. The 190 times .12 gives you the twelve percent. So 190 X 1.12 is a simple calculation that will give you the answer. We don't normally think that multiplying something by one could ever be the least bit useful, but it is useful. What mathematical property does this solution illustrate?
