Daniel has 20.
How much money will Daniel have left if he buys the cookies?
To solve this problem, let's work through it step-by-step:
Step 1: Daniel starts with \10 \).
Step 2: He wants to buy cookies costing \20 \).
Using the subtraction formula to find the remaining money:
\text{Remaining Money} = \10 - \
This calculation yields:
\10 - \20 = -\10\)
This result means Daniel will have -\10\) left, indicating he lacks 10 to make this purchase.
The correct solution to the problem is \(\boxed{-10}.
a is negative number.
b is negative number.
What is the sum of a+b?
A negative result means the person doesn't have enough money! The negative number shows how much more money they need. In this case, Daniel needs $10 more to buy the cookies.
Always write -$10 as your mathematical answer! This shows exactly how much Daniel is short, which is more useful than just saying 'he can't afford it.'
In real life, this represents a deficit or debt. If Daniel borrowed money to buy the cookies, he'd owe $10. The math shows the shortage clearly.
The problem asks how much Daniel has after the purchase, so we subtract the cost from his current amount: \10 - \. Flipping it would answer a different question!
Look for clues: when the amount being subtracted is larger than what you start with, expect a negative result. This happens in deficit or shortage problems.
