Sometimes, multiplying two numbers with similar digits might take us a few seconds to accomplish. But today, we have a math trick for multiplying numbers with the same first digit!

When two numbers have the same first digit and their last digits add up to 10:
๐ญ.) Multiply the first digit by the next whole number.

๐ฏ.) Put the answer at the end!

๐ญ.) 34 x 36
