What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Bridget was flying her new kite at an elevation of 85 feet.

And, A strong gust of wind caused the kite to drop 20 feet.

Now,

Since, Bridget was flying her new kite at an elevation of 85 feet.

And, A strong gust of wind caused the kite to drop 20 feet.

So, We get;

The elevation of kite = 85 - 20

                                = 65 feet

Thus, The elevation of the kite will be 65 feet.
