## Maths worksheets for your kids – teach addition, subtraction & multiplication with these

Published on Apr 9, 2018 in Templates

Nishanth & Nakshatra, my kids are now 8 years old and learning mathematics at school. Very soon (from this Saturday), they will have 2 weeks of school term break. As a stay at home dad, I shudder at the thought of school holidays. So this time, I have an evil plan. I made maths worksheets for them. Everyday, I will print one and ask them to complete.

If you are a stay at home parent and want to keep your kids busy for a few minutes every day, grab a copy of this and give it a go. Keep in mind that the workbook uses RANDBETWEEN(), so the numbers change every time. If you have multiple kids, print multiple copies. There are no answer sheets, so when you need to check the answers, you too must calculate them by hand.

Published on Sep 18, 2017 in Learn Excel

Time for some good, old fashioned VLOOKUP love. Let’s say you are writing VLOOKUP()s to get data from an unusually fat table, ie one with heaps of columns. You want to get to lookup ID in first column and get thingamajig in what is that column number. Well, better get counting from 1 and after 19 seconds and lots of squinting you arrive at column number 53 – which has thingamajig.

If this sounds like your VLOOKUP routine, check out these three amazingly simple tips to save some time and effort with your lookups.

Imagine you run an office furniture company. You want to stop reordering two brands of furniture – Relaxer (a type of chair) and Boca Top (a type of table). You currently have 20,000 Relaxer chairs and 5,000 Boca Tops. These are valued at \$200,000 and \$100,000 respectively. When sold, they will yield \$100,000 and \$25,000 gross profit.

## Reshaping your data easily – Case study [Pivot tables FTW]

Published on Mar 16, 2017 in Learn Excel, Pivot Tables & Charts

Late. Jayaram, my uncle is also a teacher. When I was a kid, I used to spend a lot of time with him, learning all sorts of things. He taught me chess, maths and so many life lessons. I remember one such lesson very vividly.  One day, he asked me to do something. I did it in a very long way. After seeing me struggle for several minutes, he chipped in and showed me how to do it easily. He then said, “when someone asks you where your nose is, you don’t twist arm around your head. You just point to your nose directly.”

The idea is that when you have a direct, simple way to do something, you should use it.

Nose and pivot tables… how are they connected?

We are coming to the point. Read on for full case study and solution.

## An odd lookup problem [Formulas]

Published on Dec 6, 2016 in Excel Challenges, Learn Excel

Let’s say you have some employee data in employee name, manager name format. But the data is all in one column, with odd rows containing employee names & even rows containing manager names. Something like above.

And you want to find out who is the boss for a given employee. Say, “Andrea Nichols”.

Your regular MATCH() formula for Andrea over the data range returns wrong answer as it will find first occurrence of Andrea (which in this case happens to be on even row, hence a manager record).

So how would you write the lookup formula?

## Analyzing 300,000 calls for help [case study]

Published on Aug 24, 2016 in Analytics, Learn Excel, Pivot Tables & Charts, Power Pivot

Over the weekend, I got an email from Mr. E, one of my students. Mr. E works at a police department in California and as part of his work, he was looking at calls received by police. Whenever police get a call for help, multiple teams can respond to the call and go to the location. All of these dispatches are recorded. So a single call can have several such dispatches. And Mr. E wanted to findout which team responded the first. The problem?

Finding the first responded team is tricky.

Today let’s take up this problem as a case study and understand various methods to solve it.  We are going to learn about writing better lookups, pivot tables, power pivot and optimization. Put on your helmets, cause this is going to be mind blowingly awesome.
