Pemdas means parentheses exponents Multipacation division Add Subtract Hope this helps :)
First, calculate the expression inside the parentheses: (29 + 18 = 47) and (17 - 8 = 9). Then, add these results: (47 + 9 = 56). Finally, divide by 8: (56 \div 8 = 7). Thus, the value of the expression is 7.
In the absence of parentheses, multiplication and division are carried out before addition and subtraction. In this case, add 5 to whatever is happening with the five and the two.
To speed up the addition of the expression 4 plus 6 plus 5, you can place parentheses around the first two numbers: (4 + 6) + 5. This grouping allows you to first add 4 and 6 to get 10, and then simply add 5, resulting in a total of 15.
Add multiply what is in parentheses and the number that is on the outside of the parentheses that is to the right or to the left.
removing the parentheses in a math problem
If you know the value of "n", you can replace it in the expression, then add. Otherwise, you have to keep them separate. You can still factor the expression, if you like, but that really won't make it any simpler.
To solve this expression, you must follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right). So, first, you would divide 18 by 3 to get 6. Then, you would multiply 6 by 4 to get 24. Finally, you would add 6 to 24 to get a final answer of 30.
You can expand the first expression in parentheses, then add or subtract like terms.
To solve this expression, we first need to calculate the value inside the parentheses: 2 multiplied by 6 equals 12. Then, we divide 24 by 12, which equals 2. Next, we add 8 to 2, which gives us a final answer of 10 after subtracting 4.
the parenthesis take precedence in the order of operations. The operations inside the parenthesis are taken first. Example 6 - 2 + 3 without parenthesis, you take addition/subtraction in order from left to right. 6 -2 = 4, then add 3 = 7 Now add some parenthesis. (6 - 2) + 3 Note that we do the (6-2) first because it's in parentheses, then add 3 (4) + 3 = 7 6 - (2 + 3). Now perform (2+3) first = 5, then 6 - (5) = 1.
change the sign and do the opposite operation.
