3 + 4 + 102 × 7 − 6 = how would i do this?
use pemdas
first multiply 102*7=714
then do addition and subtraction
714+3+4-6=115
ok thank you guys this site is good
if they have () you do those first right like this problem (3 + 4) + 102 × (7 − 6 you would do 3 + 4 and then 102 or?
its 715
To solve this expression, we follow the order of operations, also known as PEMDAS:
1. Parentheses: If there are any parentheses, simplify the expressions inside them first. However, in this expression, there are no parentheses.
2. Exponents: If there are any exponents, evaluate them next. But again, there are no exponents in this expression.
3. Multiplication and Division: Perform any multiplication or division from left to right. We have multiplication here, so we'll do that next.
4. Addition and Subtraction: Finally, carry out any addition or subtraction from left to right.
Now let's solve the expression step by step:
3 + 4 + 102 × 7 − 6
Step 1:
Since multiplication comes before addition or subtraction, we first multiply 102 by 7:
102 × 7 = 714
Now we have:
3 + 4 + 714 − 6
Step 2:
Addition from left to right:
3 + 4 = 7
Now we have:
7 + 714 − 6
Step 3:
More addition:
7 + 714 = 721
Now we have:
721 − 6
Step 4:
Finally, subtract:
721 − 6 = 715
Therefore, the solution to the expression is 715.
