Is it adding, multiplying or dividing or subtracting?

Adding. example if the lenght of rectangle is 4 and width is 2 then to work out the perimeter you do this: 4+2+4+2= 12 = perimeter.

Similar to speaking another language you need to think in terms of the different number system, which amounts to re-learning the addition and multiplication tables.\n\nFor instance in octal or base 8, there would be some differences.  Sure 1 + 1 = 2, and 2 + 2 = 4, but 4 + 4 = 10!!\n\nWith a little practive you could even do multiplication and division, but like decimal, it is still easier to use a calculator.

there are several methods,\n\nalmost all mathematical calculations like add, subtraction...... have many ways to calculate......\n\ncheck the website below to find alternate ways to calculate

balanced is the best answer, although constant would be correct as well....or if you're looking for a numerical answer, it would be 0

First you must distribute the 2 into the parenthesis, so instead of (5x-7), it becomes 10x-14. Then look at the 3x2, which becomes 6. Then you add your two new numbers, 6+10x-14, which can be simplified to 10x-8. \n\nYour answer: 10x-8\n\nPlease Excuse My Dear Aunt Sally. (use this expression to learn the rules in which operation to do first)\n\nParenthesis Exponents Multiplication Division Addition Subtraction.\n\nGood luck!

try working with BODMAS (BRACKETS Of Multiplication Division Addition Subtraction) and of course equalising the denominator. Hope that helps

This is actually elementary math. If you remember the order of operation, it helps. \n\nStep 1: Do the part of the problem in the parenthesis.\n  Example: (4/3)= 1.3333333333 (you get where this is going)\n\nStep 2: Take that answer and multiply it by the named multiplier.\n  Example: 1.33333 * 12= 16\n\nStep 3: Take the result of that transaction and devide it by the named devisor. For this method don't use the fraction way, and don't use a calculator. Do a basic devision problem like you were taught in the 3rd grade using the "bracket."\n  Example: 16/13 = 1  (13 goes into 16 1 time)\n\nStep 4: Subtract the 13 from the 16 and it will give you your remainder.\n  Example: 16/13 = 1   16-13= 3\n\nThe answer when written correctly isn't with a decimal but would look like this- 1 R3.\n\nAlso for a little note for this- Order of operation:\nP (parenthesis)\nE (exponents)\nM (multiply)\nD (devide)\nA (addition)\nS (subtraction)\n\nHope this helps!

L= a + (n-1)d subtract a\nL-a=(n-1)d    divide by d\n(L-a)/d=n-1    add 1\n1+(L-a)/d=n\nn=1+(L-a)/d

A previous answer was incorrect. It is\n\n-4x(x+3y)(x-2y)

I'd say 0. You cant multiply anything with 0. And dividing it by 0 equals 0... \nSo 0

2points answer.\n\nTry again.  Your question is unreadable.\n\nDon't use x as both a variable and an operator.  On that first one, which side of the multiplication is the variable x on?\n\nI don't understand what the third one is trying to say at all.\n\nUse * for multiplication, use / for division.\n\nAnd most importantly, what answer do you want from this?  You aren't showing any equalities or inequalities.  The second one shows five variables, so there aren't enough expressions to solve them anyway.

4x + (x + 2) ....... 4x + 2 is 4 times a number plus 2 and it's incorrect

I can explain this with simple mathematics..\nLet the number u choose be 'x'.\nNow double the'x' and adding 12 gives us:\n2x + 12.\nDividing this expression by 2 gives us:\nx + 6.\nSubect the no. u thought i.e. 'x' from this and what u get is 6.\nAm I correct Ma'am?
