What is one to the fourth power?
One to any power is still one. If the power is positive, you have 1 times itself over and over again, so it does not change. If the power is zero, the answer is always one, no matter the number. If the power is negative, you find the reciprocal of the expression and make the power positive. If the base of the exponential expression is 1, it is always one.
What is it equal to numerically?
Numerically, it is equal to it. This may not be the same as It if I is not the same as i. Please note that in this context, it does not matter what I am, only what i is. It is possible that it is not a single variable but denotes the product of i and t, in which case it is numerically equal to the product of the numerical value of i and the numerical value of t. A further possibility is that i is not simply one of two numerical variables being multiplied together but the imaginary square root root of -1. In that case it is simply t times the imaginary square root of -1. In the complex plane, the numerical equivalent of it would be the ordered pair (0,t).
Why does 5 plus x and x plus 5 the same expression?
When adding, the order does not matter. It's called the summation property.
How can the mass of a coin be decreased?
You cant, the mass will always be the same, NO matter what.
Will density always stay the same no matter what size the object is?
Density of the substance will always stay the same. Density of the object will also stay the same if solid, no matter the size, but not if it is carved out. That is why a steel boat can float
You will always get the same result in a numerical expression no matter the order in which you perform the operations true or false?
False. Consider the expression 10 - 9 - 8 and let the brackets denote the operation to be performed next (if there are more than one). Then 10 - (9 - 8) = 10 - 1 = 9 While (10 - 9) - 8 = 1 - 8 = - 7
Will you always get the same result in a numerical expression no matter the order in which you perform the operations?
No. Here is a simple counterexample: 1 + 2 x 3 The answer is either 7 (if using the standard convention of doing the multiplication first), or 9 (if you ignore this standard and do the addition first). When doing a series of only additions, or only multiplicatons, you can do the additions (or the multiplications) in any order.
Does it matter in which order we do each operation?
Yea because the collection of rules that define which procedures to perform first order to evaluate a given mathematical expression.
Why is zero times a number always zero?
Because if you try to multiply nothing, you will always end up with nothing. so no matter what number you multiply 0 to, since 0 has no numerical value, the answer will always be 0.
What is 'a bargain's a bargain' idiomatic expression?
This is not an idiom because it means just what it says. If something is a bargain, then it is always a bargain. It doesn't matter what the circumstances are.
Does the order in which you perform operations in a numerical expression matter?
Yes, unless all of the operations are additions, or all of them are multiplication. Otherwise, changing the order will change the result. The order of operations is determined by parentheses, or if none are present, by the PEDMAS sequence.The order in which mathematical operations must be done has the acronym PEDMAS or PEMDAS. PEDMAS or PEMDAS, no matter how you spell it, gives the correct order for mathematical operations: 1. P - Parentheses, 2. E - Exponents, MD - Multiplication and Division, AS - Addition and Subtraction.
Chenists perform experiments to find out how different kinds of matter can change and what?
Matter
Why do chemists perform experiments?
Chemists perform experiments to find out different kinds of matter can change.

What is a math experssion?
If you mean Expression, then a math expression is any collection of numbers, variables, and operations with no given answer Examples of Expressions: 2+2 2x+7 53+7f Examples of what are NOT expressions (AKA, Equations): 2+2=4 2x+7=y 10x+7=0 The difference is all in whether or not you have a given answer on the other side of the "=". It doesn't matter whether or not it gives you the numerical value of it. So, a variable is still a possible answer to an equation to make it not an expression.
What do chemists perform experiments to find out what different kind of matter can change what?
not to sure about matter but ill give it a try
What is the difference between density and matter?
The difference is that Density is one way of measuring matter, its a math expression. While Matter is a physical substance.
