**Step 1:** Since the no.s end with one our answer will contain the last digit as **1**. Have that in mind.

**Step 2: **Now **add both the tens digits **i.e., (x + y) this is you tens place. (In case of double digit add it after step 3)

**Step 3: **Again take those two previous no.s and now **multiply them **i.e., (xy) this will give you the hundreds place in case of a single value or also a thousands place along with it if it is a double digit.

Finally put them all together and that's your answer

e.g 41 x 61

Ones digit:1

Tens digit:

ones digit: 1

tens digit: 10 so, 0 (1 will be carried)

Hundreds digit: 24

Final answer: 2501

Squaring numbers ending with 5 is a simple trick that you must have in your sleeve.

**Step 1**: Multiply the ones digit. i.e., 5 x 5 = 25

**Step 2**: Multiply the no. and the next no. i.e **n(n+1)**.

Now write the two no.s together and that's the final answer you'll obtain.

e.g 35^2

5 x 5 = 25

Now 3(3+1) = 3(4) =12.

Writing the no.s together we get the answer 1225. which is the square of 35.

*Now try to re-trace the same pattern in the above picture.*
