I have many favorite Hobbies. I love to read, I like to ride a bike, and I love the story. But my main hobby is drawing. I started drawing when I was little. Mother and father very often gave me pens in a variety of colors, colored pencils and a beautiful white paper for drawing. I like to portray on a clean sheet something beautiful, plants, animals, sometimes people. So often I've done cards for mom and dad. However, first my pictures were not the best. Something was awry, something that did not happen. But I always continued to draw. Now, I think I can draw very well. My works hang on the walls in my room. I often send your creations to competitions of children's drawings and often receive diplomas and prizes. Moreover, I go to art school. I like it very much. In art school there is an atmosphere of skill and creativity. We draw still lifes, sometimes people. In the summer we go to picnic and draw nature, flowers, forest, trees, houses. Now my drawings are pretty good. But someday I want to learn to draw like the great Russian painters I. Shishkin, I. Aivazovsky, K. Bryullov and! I'm sure I'll be able to draw even better if I tried.
1) 1,4-2,5=-3,5(я делаю так:если мы вычитаем большее от меньшего, я просто их складываются в уме, а потом просто пишу ответ со знаком - , например, 1,4+2,5=3,5 и ответ в первом выражении будет -3,5. 2) -0,25+0,28=0,3( для удобства, я поменяла их местами и.к. между ними плюс: 0,28-0,25, т.к. от перестановки слагаемых СУММА не меняется. 3)-1,27-2,15=-3,42(можно делать как пример 1) 4) -5,6+4,4=-1,2(когда есть одно отрицательное число и одно положительное, при сложении, мы берём знак большего числа. Ты.е. мы можем просто вычесть 5,6-4,4 и поставить знак большего числа т.е. минус.
