Understanding the Basics of Subtraction
Subtraction is one of the fundamental arithmetic operations. It involves finding the difference between two numbers. In this case, we’re subtracting 1170 from 1299. To do this efficiently, it’s helpful to align the numbers by place value: hundreds, tens, and ones. (basic math, arithmetic operations, subtraction basics)
Step-by-Step Guide to Calculate 1299 Minus 1170
Follow these steps to subtract 1170 from 1299 accurately:
- Step 1: Write the numbers vertically, aligning the place values:
1 2 9 9 -1 1 7 0 
- Step 2: Start subtracting from the rightmost digit (ones place). Since 9 is greater than 0, subtract directly: 9 - 0 = 9.
- Step 3: Move to the tens place. Here, 9 is less than 7, so borrow 1 from the hundreds place (12 becomes 11, and 9 becomes 19). Now, 19 - 7 = 12. Write down 2 and carry over 1.
- Step 4: At the hundreds place, after borrowing, you have 11. Subtract 1 from 11: 11 - 1 = 10.
- Step 5: Finally, at the thousands place, subtract 1 from 1: 1 - 1 = 0.
Putting it all together, the result is 129. (step-by-step subtraction, math tutorial, calculation guide)
💡 Note: Always double-check your borrowing steps to avoid errors in subtraction.
Quick Tips for Mental Math
If you prefer mental math, here’s a shortcut for 1299 minus 1170:
- Notice that 1170 is close to 1200. Subtract 1200 from 1299: 1299 - 1200 = 99.
- Since we subtracted an extra 30 (1200 - 1170), add 30 back to 99: 99 + 30 = 129.
This method is faster and works well for numbers close to round figures. (mental math tricks, quick calculations, math shortcuts)
