Fear can be overcomed by love and creativity. Specially for arithmetic, which we learn first, there is no creativity. At a later stage when we get to know about algebra and geometry, we find them more interesting because in algebra we can use our brain to fix a sum with a formula and in geometry we draw lines. But in our daily life, we use arithmetic only. The conventional method of arithmetic is primarily a no-brainer. Vedic Mathematics help a lot in this regard, where one can use formula for arithmetic too! I have seen that people start loving arithmetic after learning Vedic Mathematics. So, when love for mathematics comes in, fear goes out. One can do huge additions, subtractions, multiplications, divisions etc by putting them in one of the techniques or the other. With practice, one can also calculate mentally and say the answer straight away. It teaches to use the Brain Calculator. So, it's creative too! If we can generate interest in arithmetic in early ages, there won't be any further fear in mathematics.
