An answer to the "When am I going to need this?" question I always heard in science and math class

We've all heard someone ask when they would need to use what they learned in class in the future. So I decided to come up with a simple answer that kids might actually like.

I'm going to use algebra as my example, the one we most commonly used day-to-day, we use it for budgets, shopping costs estimates, etc.; but when you're a kid in high school, (or if you're one of the smarter cookies and learning it in middle school), these examples don't really connect with you yet because you're still a kid and those examples usually apply to adults. 

So how might a kid use algebra in a day-to-day fashion? 

Simple, video games.

Be it for saving up to buy one, or actually playing one, kids still use algebra all the time without even realizing it. They use it when figuring out how many resources they need for a build or a crafting recipe. It's used when they try and figure out how many quests/adventures they need to go on before they've saved up enough gold for that cool new armor/weapon that they just unlocked in the market. Kids use algebra more often than they think, and that's what you need to point out to them.

This applies to other topics of learning too, in FPS games you use physics every time you shoot a gun (bullet drop for snipers) or throw a grenade, redstone in Minecraft is very similar to programming, building games teach architecture and sometimes even structural engineering. Video games can be a means of learning rather than it's usual portrayal as a harm to learning, so long as you know how to connect the topic to the game.
