There seems to be a symbol between 2 and 7 that has been rejected by the browser.

|6| = 6 (The absolute value of 6 is 6, the same number you started with.) 6 = 6 (The absolute value of the absolute value of 6 is 6.)

None because the numbers 4, 2 and 6 can't be considered to be an equation.
The expression would be written as 16 The value of the expression is 1. 1 x 1 x 1 x 1 x 1 x 1 = 1

An expression that has the same value as another expression is called an equivalent expression. For example, the expressions (2(x + 3)) and (2x + 6) are equivalent because they simplify to the same value for any value of (x). Equivalent expressions can be formed through various algebraic manipulations, such as distributing, factoring, or combining like terms.

To find the input value that produces the same output as the expression (3 \times 2 \times 1 \times 3), we first calculate the output. This expression simplifies to (3 \times 2 = 6), then (6 \times 1 = 6), and finally (6 \times 3 = 18). Therefore, the input value that produces the same output value is 18.
When an expression is expanded, its value remains the same; however, the form of the expression changes. Expansion involves distributing and simplifying terms, which can make the expression more straightforward to understand and manipulate. For example, the expression ( (x + 2)(x + 3) ) expands to ( x^2 + 5x + 6 ), but both forms represent the same mathematical relationship. Thus, while the representation changes, the numerical value calculated from the expression does not.

The value of the expression (2^6) is calculated by multiplying 2 by itself six times: (2 \times 2 \times 2 \times 2 \times 2 \times 2). This equals 64. Therefore, (2^6 = 64).
(6 - 2)*4/8
5(5) is 25. 3(-2) is (-6). The expression becomes 25 - (-6). When subtracting a negative number, you actually "add the opposite," so the expression is now 25 + 6 (positive 6 is "the opposite" of -6); the value is 31.
If you mean: 3+4+6+2*(58) then it is 129
It is 6a + 12, an expression which cannot be evaluated without the value of a.
To evaluate the expression (12 + 18 \div 6 - 2), we follow the order of operations (PEMDAS/BODMAS). First, divide (18) by (6) to get (3). Then, the expression simplifies to (12 + 3 - 2). Finally, calculating this gives (12 + 3 = 15) and (15 - 2 = 13). So, the value of the expression is (13).
