Representing debts and losses as negative integers and profit as positive, the financial equation is -850 + 1200 – 450. Simplifying this sequence shows a final standing of -100, a net debt of 100 rupees.
A spice trader takes a loan (debt) of rupees 850. The next day, he makes a profit (fortune) of rupees 1,200. The following week, he incurs a loss of rupees 450. Write this sequence as an equation using integers and calculate his final financial standing.

We can represent financial transactions using signed integers where debts and losses are negative, and profits are positive. The trader starts with a loan of -850 rupees, adds a profit of +1200 rupees, and adds a loss of -450 rupees. The complete sequence forms the integer equation -850 + 1200 – 450. Adding the numbers together gives 350 – 450, which equals -100. His final financial standing is a net debt of 100 rupees.
