Feeling math-anxious?

Many students ask me this question.

** “Can I ace the GRE math, if I have a non-math background?” Yes, you can.**

Remember GRE tests you on math reasoning…

* To overcome anxiety, You need to learn math concepts.+ You need to develop math skill-sets too.*

Formula/theorems (Area of the circle, HCF and LCM of numbers…) are the math concepts.

**So what are the math skill-sets?**

** **Definition of a skill-set: A skill-set is the combination of knowledge and abilities that you’ve developed through your life and work. You use these skills-sets to tackle problems.

We, at semantics, have developed modules, which can hone a students math and verbal skill sets.

Let me take you through one math skill-set.

** Problem Decomposition **

**Definition: **Decomposition is the process of breaking a problem down into smaller parts to make it easier to tackle.

If you have a non- math background, you might find it difficult to comprehend word problems.

One way to analyze word problems is – break problems into meaning-full chunks.

You need to

- break the problem into 2 or more segments.
- Analyse each segment.
- Infer data (if necessary)
- Diagram information…

Only after all this, you write equations and solve..

Let me demonstrate the above process via a math question

Lets take this problem and break it into segments.

**Segment 1: “Each machine produces 1 toy every 3 minutes”**

**Segment 2: “After replacement : 40% of machines produce 1 toy every 2 minutes”**

When you process segment 2, you should also infer additional information.

This information is not explicitly mentioned.

**Inference: If 40% of the machines produce 1 toy every 2 minutes, then 60% of the machines produce 1 toy every 3 minutes**

** ****Segment 3: “Percentage increase in the number of toys produced in 60 minutes.”**

After breaking the problems into segments, you should use one of the many problem solving approaches.

Lets use this approach: **substitution of numbers.**

Assume 100 machines are there initially

** Segment 1:**

Total time is 60 mins.

1 machine produces a toy every 3 minutes . Hence 20 toys are produced by 1 machine in 60 mins.

There are totally 100 machines.. Hence number of toys produced = 100 x 20= 2000 toys

**Segment 2:**

Total number of machines = 100

type 1: 40% of the machines (i.e. 40 machines) produce 1 toy every 2 minutes,

type 2: 60% of the machines (i.e. 60 machines) produce 1 toy every 3 minutes

Lets calculate number of machines produced by type 2 first..

1 machine produces a toy every 3 minutes . Hence 20 toys are produced by 1 machine in 60 mins. Totally 60 machines.. Hence 60×20= 1200 toys

Let us calculate number of machines produced by type 1.

1 machine produces a toy every 2 minutes . Hence 30 toys are produced by 1 machine in 60 mins. Totally 40 machines.. Hence 40×30= 1200 toys

so totally 1200+1200 = 2400 toys are produced.

** Segment 3:**

Percentage change = (2400-2000)/2000 x 100 = 20%

Hope you have understood this problem solving process.

Even if you have a non-math background, you can learn these processes and apply them on a wide genre of questions.
