To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number. To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
What’s the value of expression?
The value of a mathematical expression is the result of the computation described by this expression when the variables and constants in it are assigned values. The value of a function, given the value(s) assigned to its argument(s), is the quantity assumed by the function for these argument values.
What is the value of -|- 4?
The absolute value of (−4) , written as |−4| , is equal to 4 because −4 is 4 places away from zero. If you make that number negative, then your answer is 4.
Which is the value of this expression when a =- 2 and B =- 3?
IF your expression “a-2 b-3” is meant to be “(a-2)(b-3)” then Bill is correct, and the answer is -5 when a is 3 and b is -2. However, if you mean”a – 2b -3″ then, substituting the values you gave for a=3 and b=-2, that would be “3 – 2(-2) -3” which is the same as “3 +4 -3” and the expression evaluates to 4.
What is the value of 8?
The absolute value of 8 is 8.
What is the value of 6?

What is the value of log 375 2 Root 5?
For 375, you can write it as 125 * 3, now 125 is 5 power 3. So, log 375 = log 125*3 = log 125 + log 3. As 125 is 5 power 3, log 125 = 3 log 5. 2 log √5 = log 5.
What is the value of 7?
