14000
Step-by-step explanation
Step 1
add the numbers ( normally)
Step 2
now, round the result
If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is. Any digits after that number become zeros, or drop-off if they're located after the decimal point. This is called rounding down.
If the next smallest place value is greater than or equal to five (5, 6, 7, 8, or 9), you increase the value of the digit you're rounding to by one ,
because 178 is smaller than 500, we let 14000
I hope this helps you
