A spice trader takes a loan (debt) of ₹850. The next day, he makes a profit (fortune) of ₹1,200. The following week, he incurs a loss of ₹450. Write this sequence as an equation using integers and calculate his final financial standing.
Answer
Given,
Loan (debt) = -₹850 (negative as it is a debt)
Profit (fortune) = +₹1,200 (positive as it is a fortune)
Loss = -₹450 (negative as it is a loss)
Writing the equation using integers :
⇒ (-850) + 1200 + (-450)
⇒ -850 + 1200 - 450
⇒ 350 - 450
⇒ -100.
Hence, the spice trader's final financial standing is -₹100, which means he is in a debt of ₹100.

Why does a negative times a negative equal a positive? Think of it in terms of action and debt. If a negative number represents a debt, then multiplying by a negative number represents the removal of that debt. (Hint: If someone takes away (–) four of your debts that are each worth ₹3 (that is, –3), you are effectively ₹12 richer! Therefore, (–3) × (–4) = +12.)
