mathematics - Move one thing in the equation




$1484 / (7 / 9) = 19$


Make the equation true by moving one continuous shape or operation in the equation.



Answer



In a similar method to Vaelus' answer, take the



empty space above the equation connecting the 8 and the second /, like so: step 1



EDIT: The continuous shape that I've extracted is given by the blue here, which fits the requirements of the original question:



step 2




If you then



rotate this 135 degrees clockwise, you will see that the slash is now vertical and looks like a 1, and the 8 looks like two diagonal zeros step 3



Either



shrink this



or




change the distance of the two pieces from the viewer to simulate zooming. It will look like the following: step 4 Superimpose this back on the remainder to get this: step 5



Which gives us



the modulo operator, and the equation 1441 % (79) = 19



Which is true
