Pen & Paper V
On a sheet of paper, write the following (incorrect) equation:
1 2 x 1 6 = 4 3 2
The challenge: Draw four lines, three on the left side of the equation and one on the right, to make the equation valid.
Change the = into a not-equal sign.
Manipulate the paper in any way.
Draw any curves.
Draw any dots or points.
HintTry to find a solution that does not involve the use of addition or subtraction.
AnswerOn the right side of the equation, draw a diagonal line between the 4 and the 3, such that the right side of the equation is 4/32. On the left side of the equation, draw an identical line between the first 1 and the 2, and draw a small 7 to the upper-right of the 2.
You should have:
1 / 2^7 x 1 6 = 4 / 3 2 (In this case, the ^ indicates that the 7 is an exponent.)
