Question

2·5 - 3·5 =
-10 ÷ 2·8 - 4 =

Explanation:

Step1: Calculate \(2 \cdot 5 - 3 \cdot 5\)

First, perform the multiplications: \(2 \cdot 5 = 10\) and \(3 \cdot 5 = 15\). Then subtract: \(10 - 15 = -5\).

Step2: Calculate \(-10 \div 2 \cdot 8 - 4\)

Follow the order of operations (multiplication and division from left to right first). First, \(-10 \div 2 = -5\). Then, \(-5 \cdot 8 = -40\). Finally, subtract 4: \(-40 - 4 = -44\).

Answer:

For \(2 \cdot 5 - 3 \cdot 5\), the answer is \(-5\).
For \(-10 \div 2 \cdot 8 - 4\), the answer is \(-44\).
