# Order of operations-lesson

3+5×6, 2-5×3, 8+4÷2 and so on.

For the first expression, we get value 48 because we wrongly calculate it as:

3+5×6=8×6=48

we just go from left to right. But, we need to be careful here!!!

Operations have their order, and it is:

1. × and ÷,

2. + and -.

This means that we first do multiplication and division and after addition and subtraction. So, correct calculation of our expression 3+5×6 is:

3+5×6=3+30=33.

Similarly, we get that:

2-5×3=2-15=-13,

8+4÷2=8+2=10.
