Still need help with these 2 problems
16 ÷ (-2) * (-4) OVER 2^3 + 4
4 - (-3) +1 OVER 2-2 ÷ (-2)
16 ÷ (-2) * (-4) OVER 2^3 + 4
-8 * -4 = 32
______________________
(2 * 2 * 2) + 4 = 12
32/12 = 2 2/3
What do you think the second answer is?
i will give it a shot
1 + 1 =2
______________
-2 = 1
2 - 2 = 0
Zero divided by any number is 0, so this problem is wrong and can't be solved.
so why wouldn't the answer be
2 over 0
Sure! Let's go through each problem step by step.
Problem 1: 16 ÷ (-2) * (-4) ÷ 2^3 + 4
To solve this problem, we need to follow the order of operations, which is commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
Step 1: Evaluate the exponent: 2^3 = 2 * 2 * 2 = 8
Now we have: 16 ÷ (-2) * (-4) ÷ 8 + 4
Step 2: Perform the multiplication and division from left to right:
16 ÷ (-2) = -8
Now we have: -8 * (-4) ÷ 8 + 4
Step 3: Perform the remaining multiplication and division:
-8 * (-4) = 32
Now we have: 32 ÷ 8 + 4
Step 4: Perform the addition and subtraction from left to right:
32 ÷ 8 = 4
Now we have: 4 + 4
Step 5: Perform the final addition:
4 + 4 = 8
Therefore, the solution to the first problem is 8.
Problem 2: 4 - (-3) + 1 ÷ 2 - 2 ÷ (-2)
Again, we'll use the order of operations (PEMDAS) to solve this problem.
Step 1: Start with the subtraction of negative numbers:
4 - (-3) = 4 + 3 = 7
Now we have: 7 + 1 ÷ 2 - 2 ÷ (-2)
Step 2: Perform the division operation:
1 ÷ 2 = 0.5
Now we have: 7 + 0.5 - 2 ÷ (-2)
Step 3: Continue with the remaining division:
2 ÷ (-2) = -1
Now we have: 7 + 0.5 - (-1)
Step 4: Perform the final addition and subtraction:
7 + 0.5 = 7.5
7.5 - (-1) = 7.5 + 1 = 8.5
Therefore, the solution to the second problem is 8.5.
