So far, on this week’s math kick, we’ve looked at Algebra, variables, and constants. Today, we continue with an operation.
Turning, once again to MathIsFun.com, we find that an operation is defined as “a mathematical process,” with the most common being to multiply, divide, add, and subtract.
In our example, Y – 5 = 10, the operation is to subtract 5 from the value of Y.
The “-“, or minus sign, is an operator, which MathIsFun.com explains as “a symbol (such as +, −, ×, etc) that shows an operation.”
In our example, Y – 5 = 10, “-” is the operator, telling us that 5 is to be subtracted from the value of 5 Y.
Our math kick this week started on Monday, with Algebra, and continued yesterday, with variable. Today, we look at the constant.
MathIsFun.com informs us that, with respect to Algebra, “a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number.”
In other words, it is a number whose value is known.
In our example from our post on Algebra, Y – 5 = 10, 5 and 10 are constants.
In our next post, we will finish looking at the different components of our example.
Continuing on our math kick from yesterday, we’ll move on to the variable.
At MathIsFun.com, a variable is defined as “A symbol for a number we don’t know yet. It is usually a letter like x or y.”
In yesterdays example, Y – 5 = 10, Y is a variable.
In our next post, we will continue looking at the different components of our example.
Lately, we regret the marked decrease in posting at FamilyTrivium.com. A new school year is in full swing and to say that we are busy is a definite understatement.
One of the many things keeping us busy is a marked increase in homework. In particular, Algebra has been consuming what used to be abundant free time. However, one of the Family Trivium kids hopes to be a scientist and math is must for them.
According to MathIsFun.com, Algebra is a branch of math which “uses letters (like x or y) or other symbols in place of unknown values.”
Y – 5 = 10
If we add 5 to both sides of the eauation we can determine the value of Y:
Y – 5 + 5 = 10 + 5
Y = 15
Put simply, in Algebra, we use what we do know to help us determine what we don’t know.
Going back to how to how Family Trivium started, at the spur of the moment, future posts will likely be shorter, like this one. We do this with the hope of actually making regular posts.
