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.
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
in mathematics, numerical coefficient refers to the constant multiplicative factors attached to the variables in an expression are known as Numerical Coefficient. It differs from Literal Coefficient.The Numerical Coefficient is always written in front of the variable as shown in the expression given below: , where are numerical coefficients.Numerical Coefficient is more frequently referred as Coefficient.the numerical coefficient for the term 10x4 is 10.The numerical coefficients for the expression 3x2 + x + 1 are 3, 1, and 1.
A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. An algebraic expression is an expression with a variable in it, and a polynomial is an expression with multiple terms with variables in it.
NoRestate the question: When using the order of operations to evaluate an expression would you always do multiplication before division?If this is not your question, please clarify and ask the question again. :-)No. Unless parentheses or other grouping symbols indicate otherwise, you do multiplication and division in order from left to right.
-a2 differs from (-a)2 because the brackets change the order in which operations are done. Normally, exponents are handled before addition, subtraction, multiplication and division. This means that in the first expression, -a2, we are subtracting the square of the value a. In other words, our first expression could also be expressed as -(a × a). Brackets however are used to specify a set of operations that need to be done first. This means that our second expression would instead be broken down as (-a) × (-a). The resulting difference between the two is that the first expression will always give us a negative number, and the second one will always give us a positive number (assuming imaginary numbers are not involved).
false
A
It's possible to perform other operations first. But if you try it, there's a muchbigger chance that you'll get all tangled up and your result will be wrong.
You can always write a numerical division expression as a decimal.
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
Numerical expression: 59-34*6 Algebraic expression: 5x-3x+2 A numerical expression is limited to only numbers and can always be simplified to one number. An algebraic expressuion uses terms, more specifically a variable like x, and a constant like 2.

The answer is false
All computer systems are always able to perform five basic operations. They include inputting, storing, processing, outputting, and controlling.
A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. An algebraic expression is an expression with a variable in it, and a polynomial is an expression with multiple terms with variables in it.
A polynomial is always going to be an algebraic expression, but an algebraic expression doesn't always have to be a polynomial. In another polynomial is a subset of algebraic expression.
Observational and experimental data are almost always recorded and analyzed in numerical form.
