s=0.5(70-25)40=
can u solve this for me and explain it please
s = 0.5(70-25)40
1. Do whatever there is to do inside the first parentheses you come to going
left to right. Copy everything else over.
2. If any parentheses remain with anything to do inside them, repeat step 1.
If there are no parentheses which have anything to do inside them, do the
first exponent, going left to right. Copy everything else over.
3. If any exponents remaimj, repeat step 2. If there are no exponents, do the
first multiplication or division, going left to right. Copy everything else
over.
4. If any multiplications or divisions remain, repeat step 3. If there are no
multiplications, do the first addition or subtraction, going left to right.
Copy everything else over.
5. If any additions or subtractions remain, repeat step 4. If there are no
additions or subtractions you are done.
s = 0.5(70-25)40
1. The first (only) parentheses that has something to do in it is (70-25),
so we replace (70-25) by (45), and copy everything else over:
s = 0.5(45)40
2. There are no exponents, so we go to 3
3. The first multiplication or division is 0.5(45) so we replace 0.5(45)
by (22.5), and copy the rest, the 40, over.
s = (22.5)40
There is still a multiplication, so we repeat step 3, and get
s = 900
There is nothing left to do, so that's the answer.
