Numerical expressions are math problems containing only numbers and operational symbols. Solve by first completing any computations appearing inside parenthesis, working from left to right. Then compute exponents, working from left to right. Finally, complete the multiplication and division portions from left to right, followed by the remaining addition and subtraction portions.Know More
Find the value of any portions of the numerical expression that are located inside parenthesis. Compute these values by working from left to right inside the parenthesis, doing multiplication and division first and addition and subtraction second. For example, compute (2 + 4) x (15 - 6 x 2) by first simplifying 2 + 4 to get 6 x (15 - 6 x 2) and then computing 6 x 2 to get 6 x (15 - 12). Finish computing the portion in the parenthesis by doing the subtraction to get 6 x 3.
Compute the actual value of any number in the numerical expression that has an exponent. For example, convert 2^2 to 4.
Working from left to right, compute any multiplication and division found within the numerical expression. Using this method, the expression 4 x 6 + 2 x 4 becomes 24 + 8.
Finish the problem by completing the addition and subtraction, again working from left to right. This gives the solution to the numerical expression.
Two to the fourth power is 16. This is determined by multiplying two by itself four times, which equals 16.Full Answer >

The inverse of an exponential function is a logarithm function. An exponential function written as f(x) = 4^x is read as "four to the x power." Its inverse logarithm function is written as f^-1(y) = log4y and read as "logarithm y to the base four."Full Answer >
An exponent is how many times to use the number in a multiplication. Therefore, 10 to the 8th power is 100,000,000. It is solved by the equation 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10.Full Answer >
