If you're trying to figure out what x squared plus x squared equals, y'all may wonder why there are letters in a math problem. That'south because, in the case of an equation like this, 10 can be whatever you want information technology to exist. To discover out what x squared plus 10 squared equals, you lot have to multiply x times itself. And so you lot add that number to itself to get your terminal answer.
Examples of X Squared Plus X Squared
Hither are some examples of that equation to make it easier to sympathize. If x equals two, then ten squared, or ten times itself, equals 4. Add four to itself, and you get 8. Therefore, 2 squared plus two squared equals 8.
To employ another example, permit'southward run into what happens when 10 equals 3. In that case, 10 squared equals 9. Then, 9 plus 9 equals xviii. The beauty of this equation is that x can equal annihilation, and you tin solve it using whatever value y'all want for x.
Math that Uses Letters
We call mathematics that uses messages to have the place of dissimilar values algebra. Algebra uses symbols ― in most cases, letters ― to represent quantities that don't necessarily accept the same value all the time. These quantities are called variables, and you lot tin figure out what those variables hateful when y'all apply algebra.
Equations are like sentences that explain the relationships between numbers and variables. You lot figure out what the variables in an equation are by solving it. When you solve an equation in algebra, you suspension it downwards to its simplest form and discover what the variables mean.
A Brief History of Algebra
Since ancient times, mathematicians take worked with unknown variables in dissimilar means. Islamic scholars began to give the science of working with variables a proper name. They called this type of math the "science of restoration and balancing," and the Arabic word for "restoration," or "al-jabru," became the root word for the discussion "algebra."
As mathematicians in the Center Ages experimented with the principles of algebra, they realized they could solve equations for two- and iii-dimensional items, which led to even more discoveries of what algebra could do. Modern scholars accept constitute even more than complex equations that algebra tin can solve.
Algebra in Everyday Life
Y'all may have heard people say that yous'll never utilize algebra in your everyday life, only you'd be surprised at how often you apply algebra. Algebra comes in handy when you're trying to figure out how much a grouping of items costs per particular. When you're trying to figure out how to split a eating house beak or how much gas you lot can buy for a certain amount.
Y'all can utilize algebra to figure out the dimensions of a room or even as you lot make up your shopping list. Algebra is a versatile form of math that you lot utilise more often than you lot might recall and, sometimes, you don't fifty-fifty realize that yous're solving math problems.
Why It's Important to Learn Algebra
Learning algebra is important for more than just solving equations. Educators consider algebra the gateway to higher forms of math, so if yous or your kid wants to explore a career in science or technology, algebra tin unlock then many more new ideas.
Algebra can also help students with critical thinking and logic skills. Using algebra is like practice that helps brand your brain stronger. Putting algebra to utilise in your everyday life can assist you in and so many ways.
