Factor Fiona

Fiona had learned to see these hidden seams when she was ten years old. Her uncle was a cabinetmaker, and his workshop always smelled of sweet cedar shavings, mineral spirits, and warm wood glue. She used to sit on a three-legged stool in the corner, watching him work.

He would stand before a finished oak dining chair, running his rough hands over the smooth backrest. To Fiona, the chair was just a chair. But her uncle saw something completely different.

"Look here, Fee," he would say, pointing to a seamless corner. "This isn't just one piece of wood. It's a mortise and tenon joint. The peg goes in here, and the pocket holds it tight."

He would tap the joint with a wooden mallet, explaining how the grain of the oak ran.

"Once you build a chair, you can never look at one as just a seat again," he told her, wiping sawdust from his apron. "You see the joints. You see the pegs. And once you know how a thing is put together, you can fix it, or copy it, or change it entirely."

Fiona took that lesson and carried it into her math notebook.

Numbers stopped being flat drawings on a page. Thirty-six wasn't just a symbol anymore. It was a little wooden chest made of six sixes, or nine fours, or three twelves. Each number became a kit of parts. When a difficult multiplication problem landed on her desk, she didn't panic. She simply reached for her mental toolbox, found the seams, and pulled the numbers apart into friendlier pieces.

The next afternoon, Fiona found a girl named Sana staring blankly at a long-division problem. Sana was chewing on the cap of her blue pen, her notebook covered in messy eraser smudges. The screen showed a calculation that required her to multiply a large decimal by twenty-four.

"I hate twenty-fours," Sana whispered to her desk. "It's too big. I always mess up the carrying part."

Fiona sat on the edge of the digital margin, swinging her boots. "Then don't use twenty-four. Use its blocks."

Sana looked up, blinking. "What do you mean? The problem says twenty-four."

"Sure, but twenty-four is just a disguise," Fiona said, tapping her leather belt. "What is twenty-four made of?"

"Six times four?" Sana offered.

"Perfect," Fiona said. "Or eight times three. Let's use eight and three. Instead of multiplying by twenty-four all at once, multiply your number by eight first. Then, take that answer and multiply it by three."

Sana frowned, her pen hovering over the paper. "Is that allowed?"

"It's your workshop," Fiona said with a dry shrug. "You own the numbers. You can handle them however you like."

Sana slowly wrote down the first step. She multiplied the decimal by eight, which was surprisingly easy. Then she took the result and multiplied it by three. She stared at the final number, then compared it to the answer key.

"It worked," Sana said, a tiny smile breaking through her frown. "That was actually... simple. It felt like two small steps instead of one giant mountain."

"That is the secret," Fiona said, leaning back. "A hard number is just easy numbers wearing a mask. Take it apart, deal with the pieces one by one, and the scary thing falls apart in your hands."

In the margin of her notebook, Sana wrote a note to herself: Break the big numbers into factors. Do the easy pieces first.

For Fiona, the best part of the job wasn't the correct answers. It was the moment a kid stopped looking at a number with fear.

She spent an hour that Friday with Theo, a boy who used to freeze whenever a three-digit number appeared on his screen. To Theo, the number one hundred and twenty was a fortress wall. He would stare at it, his shoulders rising toward his ears, waiting for the inevitable mistake.

"Walls are only scary because you think you have to climb over them," Fiona told him. She unbuckled a small brass pry bar from her belt and handed it to him across the screen. "But this number isn't solid stone. It's just a stack of blocks. Where are the seams?"

Theo looked at the digital pry bar, then at the number 120. "It ends in a zero. So... ten is in there?"

"Exactly," Fiona said. "Ten is a massive seam. Pop it open."

Theo tapped the screen. The number split into ten and twelve. He let out a breath he seemed to have been holding for ten minutes.

"Now look at twelve," Fiona prompted. "What's inside?"

"Four and three," Theo said quickly. "Or six and two."

"Keep going," Fiona urged. "Take it all the way down."

Within a minute, the giant, terrifying one hundred and twenty was gone. In its place sat a neat row of small, manageable factors: twos, threes, and fives. They looked like clean wooden blocks ready for a building project.

"It's not a wall anymore," Theo said. He touched one of the digital twos, spinning it around. "It's just a kit."

"It was always a kit," Fiona said. "You just had to find the seams."
