Charlie is solving the following problem, and gets an answer of 15
4--2xx(5+10)divide5-3
Identify Charlie's error, and find the correct answer
Charlie has forgotten to apply the order of operations and has just worked from left to right, starting with 4--2.
The correct order of steps is to resolve the brackets (5+10)=15, then multiply -2x15 = -30, then divide -30 by 5 = -6, then 4 - -6 = 10, then finally 10 - 3 = 7
Solve.
10 + (8 x 4 - 54 ÷ 9)
Solve:
2 x -3 ÷ (-24 ÷ 4)

The Mariana Trench, the deepest part of the ocean, has a depth of approximately 11,034m below sea level. Mount Everest, the tallest mountain on Earth, has an elevation of 8,849m above sea level. What is the difference between these two heights?
remember below sea level is negative!
Difference = 8849 - (-11034) = 8849 + 11034 = 19883m
The difference in height between the peak of Mount Everest and the bottom of the Mariana Trench is approximately 19,883m
