A meteorologist tracked the increase and decrease of rain totals in inches from the previous year. This is the data for the following 4 months: January -1.34, February +2.68, March + 1.79, April -0.87. Estimate the change from the previous year by adding the totals rounded to integers.

To estimate the change from the previous year, we need to add the rain totals for each month in the current year and round the result to the nearest integer.

Let's add the rain totals for each month:

January: -1.34
February: +2.68
March: +1.79
April: -0.87

Adding these numbers together, we get:

-1.34 + 2.68 + 1.79 - 0.87 = 2.26

Now, let's round this number to the nearest integer. Since 2.26 is closer to 2 than it is to 3, we round down to 2.

Therefore, the estimated change from the previous year is +2 inches.
