Answer 2

Let's break down the expression step by step:

15 + (90 - 9) ÷ 3

First, we simplify the expression inside the parentheses:

90 - 9 = 81

Now we substitute the simplified value back into the original expression:

15 + 81 ÷ 3

Next, we perform the division:

81 ÷ 3 = 27

Now we substitute the result back into the expression:

15 + 27

Finally, we add the numbers:

15 + 27 = 42

So, the value of the expression is 42.

Moving on to the second expression:

(9 × 4 - 6 × 5) × 4 - 42 ÷ 7 + (60 - 11)

Let's simplify this step by step:

First, we perform the multiplications inside the parentheses:

9 × 4 = 36 6 × 5 = 30

So, the expression becomes:

(36 - 30) × 4 - 42 ÷ 7 + (60 - 11)

Next, we perform the subtraction inside the parentheses:

36 - 30 = 6 60 - 11 = 49

Now, the expression becomes:

6 × 4 - 42 ÷ 7 + 49

We continue simplifying by performing the remaining multiplications and divisions:

6 × 4 = 24 42 ÷ 7 = 6

The expression becomes:

24 - 6 + 49

Finally, we perform the addition and subtraction:

24 - 6 + 49 = 67

So, the value of the second expression is 67.
