# Prepare to Be Stumped By This Math Problem Meant for Fifth Graders

Math is hard. Just ask Mumsnet user PeerieBreeks, who posted a ‘simple’ math riddle meant for fifth graders to the parenting website, and ended up with more than 500 comments—many of them from adults struggling to come up with the correct answer. Here’s the riddle:

For the most part, the problem-solvers who shared their answers all believed that the man made a profit, but whether it was \$10, \$20, or \$30 seemed to be in hot dispute. Can you figure it out? (Scroll down for the answer. We’ll give you a minute …)

The wording of the riddle, not the math, seems to be what’s throwing most people off. Because the transactions in question relate to the same horse, people are looking at it as a single, four-part transaction—buys, sells, buys, sells. But the correct way to look at the problem, and figure out the answer, is to look at it as just two transactions: a man bought a horse and sold a horse. A man bought a horse and sold a horse. (The man could just as easily have bought and sold a dog in one of those transactions and it wouldn’t change the outcome.)

All of which is to say that the correct answer is: The man made a \$20 profit.

# 18 Disney Characters Just Got the LEGO Treatment

LEGO

If you’ve ever wondered what one of Disney's princesses might look like standing next to Batman or Harry Potter, now's your chance to find out. LEGO has created minifigures of 18 characters from beloved Disney movies, and they’re a pretty diverse bunch.

There are Disney princesses and heroes, like Jasmine, Elsa, and Hercules. There are offbeat favorites, like Jack and Sally from The Nightmare Before Christmas. A couple villains were thrown into the mix for good measure, and classic characters like Mickey and Minnie Mouse are also represented.

It has been a big week for both LEGO and Disney. The toy company announced the impending release of a 751-piece set that recreates the boat from Steamboat Willie, the 1928 short film that launched Mickey to stardom. The timing is also fitting, considering that Mickey recently celebrated his 90th birthday (not too bad for a mouse).

The S.S. Willie set will be available on April 1, but fans will have to wait a little longer for the Disney minifigures. Those will be available on the LEGO Store website and in stores nationwide starting May 1. Each minifigure costs \$3.99.

Until then, check out some of the figures below, or browse LEGO’s selection of Disney-themed sets.

# Disney’s Steamboat Willie Has Been Immortalized in LEGO

LEGO

Mickey Mouse recently turned 90 years old, and soon, you’ll be able to celebrate with LEGO. Steamboat Willie, the classic Disney short film that introduced Mickey Mouse to the world in 1928, has now been recreated in a LEGO set that will be released on April 1.

The 751-piece LEGO version of the S.S. Willie features grayscale bricks that recreate the original black-and-white aesthetic of the original film. The 10-inch-long LEGO boat features moving steam pipes and paddle wheels and comes with new Mickey and Minnie minifigures. It’s also equipped with a ship’s wheel, a life buoy, a buildable bell, and a working crane that can lift the vessel’s potato-bin cargo.

LEGO

The Steamboat Willie set was born out of the company’s fan-generated LEGO Ideas initiative several years ago. Creator Máté Szabó submitted the idea to LEGO in June 2016, then LEGO designers John Ho and Crystal Marie Fontan worked to adapt the set for retail sale, creating decorative elements and the new Mickey and Minnie Mouse minifigures.

LEGO

Buy the kit on the LEGO Store website for \$90 starting April 1. If you can't wait to get your LEGO fix, check out the company's other Mickey Mouse-themed products here.
