can someone explain to me in written words what is the difference between the following two statements x+2 and 2x
x+2 is adding 2 to x
2x is multiplying x by 2
what is 2(3*3)
It is 2*3*3=18.
To calculate 2(3*3), you need to follow the order of operations or the "PEMDAS" rule, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
First, simplify the expression inside the parentheses: 3*3 = 9.
Next, multiply the result by 2: 2 * 9 = 18.
Therefore, 2(3*3) equals 18.
