Question

96÷2÷12+15×(78÷13)-(33+54)

Answer 1

96:2:12+15×(78:13)-(33+54)=7

Answer 2

48:12+15*3-87=48:12-90-87=4+3=7

Answer 3

To solve this expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we evaluate any expressions inside parentheses. There are two sets of parentheses in this expression:

• (33+54) = 87
• (78÷13) = 6

So now our expression looks like:

96÷2÷12+15×6-87

Next, we perform any multiplication or division, working from left to right. In this case, we have:

• 96 ÷ 2 = 48
• 48 ÷ 12 = 4

So our expression becomes:

4 + 15×6 - 87

Next, we perform any addition or subtraction, working from left to right. In this case, we have:

• 15 × 6 = 90
• 4 + 90 = 94
• 94 - 87 = 7

So our final answer is:

7
