Question

Quizplus · Accepted Answer

The original equation $a \cdot b \div b + 5 b = a + 5 b$ is already true without any need for additional parentheses. This is because $a \cdot b \div b$ simplifies to $a$ (since $b \div b = 1$), and adding $5b$ to both sides does not change the equality.

Remove or Add Parentheses as Indicated a⋅b÷b+5b=a+5ba \cdot b \div b + 5 b = a + 5 ba⋅b÷b+5b=a+5b
