[00:00:01]Hey guys, welcome to this video. In this video we want to find the value of this expression.

[00:00:06]10 minus 6 times 10 minus 6.

[00:00:11]Are you ready to solve? Let's go ahead and get started. 10 minus 6 gives us 4.

[00:00:20]And again here inside this parentheses we have 10 minus 6.

[00:00:27]So 4 times 4 gives us 16.

[00:00:35]But this answer is not correct.

[00:00:38]Because according to the order of operations, which is PEMDAS, P stands for parentheses, E stands for exponents, M and D stands for multiplication and division, and A and S stands for addition and subtraction.

[00:00:57]First we have to do parentheses, then exponents, then multiplication or division, and then finally addition or subtraction. Remember that multiplication and division have equal priority and we have to work from left to right.

[00:01:14]And the same applies to addition and subtraction.

[00:01:17]In this expression we have one subtraction, one multiplication, and the one parentheses. Inside this parentheses we have one subtraction.

[00:01:26]Here we have a multiplication because in mathematics when a number is placed next to parentheses, it means multiplication and we usually don't write the multiplication sign for brevity. Okay?

[00:01:38]So, according to the PEMDAS, first we have to do this parentheses, then this multiplication, and then finally this subtraction. If we do this subtraction before this multiplication or this parentheses, it is wrong.

[00:02:05]>> So, first we have to do this parentheses.

[00:02:10]Inside this parentheses, we have 10 minus 6, which equals 4.

[00:02:15]So, we have 10 minus 6 then times 4.

[00:02:23]Now, in this expression, we have one subtraction and one multiplication.

[00:02:27]According to the PEMDAS, multiplication has higher priority than subtraction because multiplication comes before subtraction. So, here, first we have to do this multiplication. 6 * 4 = 24.

[00:02:46]So, we have 10 minus 24.

[00:02:51]Which equals -14.

[00:02:56]And this is our final answer to this problem.

[00:03:01]The correct answer is -14.
