Brain Game: Line Up!
Study this chalkboardÂ mathematics equation for today's Brain Game:
YourÂ goal is to move certain lines to make the two sides of the equation equal. And I want you to do it not once, not twice, but three times. First, solve forÂ puzzle #1, then (referring back to the original image) solve for puzzle #2, and thenÂ puzzle #3. Good luck!
PUZZLE #1: Make both sides of the equation equal by adding a single straight line to the left side of the equation. PUZZLE #2: Make both sides of the equation equal by removing a single straight line from the right side of the equation. PUZZLE #3: Make both sides of the equation equal byÂ moving one straight line from the left side of the equation to the right side of the equation.
HereÂ areÂ three possible SOLUTIONS.
NOTE: You may come up with different solutions than those that follow. If so, please post them in the comments. Thanks!
PUZZLE #1: In the left part of the equation, connect the top and left ends of the first plus sign to make it a 4.
Then the equation reads 545 + 1 = 546. (Alternately, use this tactic on the second plus sign, making the equation read 5 + 541 = 546.)
PUZZLEÂ #2: In the right side of the equation, remove the line connecting the top and left ends of the 4 to turn it into a plus sign.
Then the equation reads 5 + 5 + 1 = 5 + 6.
PUZZLEÂ #3: In the left side of the equation, remove the vertical bar from the second plus sign and move it to the right side of the equation, using it to form a division sign between the 54 and the 6. Then the equation reads 5 + 5 - 1 = 54 / 6.
