have stopped using our body and brain. Computers‚ calculators and internet are sources of great help but we have begun to depend totally on these inventions. For instance‚ even if we have to add a few numbers or do a small calculation we take out our calculator rather than use our brain. Our parents can still solve such problems in a jiffy without the aid of a calculator. We should try to solve our mathematical problems without using calculators this makes our mind sharp.

because we had 7 numbers and we needed to find something in common about the 7 numbers. Since we are trying to find a commonality between 7 different numbers‚ we would have to start high‚ so I started at 100 and kept finding multiples of 2-7 on a calculator and recording it on paper‚ till I eventually hit 300. I noticed that 300 had 2-6 go into it evenly‚ and 7 went into 301 evenly. This means 2-6 go into 301 evenly with 1 left over‚ and

domain‚ you divide the total amount of material by the number of x’s. 180 is the total amount of material and there are 3 x’s. So divide 180 by 3. The answer is 60. So the domain is (0‚ 60). To find the dimensions that yield maximum area‚ on the calculator press the y= button and type in the final area equation we got‚ which is 180x – 3x^2. Then before you graph‚ you press the window button and enter the domain in the Xmin and Xmax slots. So it would look like Xmin = 0 and Xmax = 60. You just leave
