How is estimation when adding and subtracting decimals

Answer

It makes equations easy so solve by mentally adding and subtracting numbers.

Explanation

Estimation means getting something close to the answer. Estimating can also be called approximating.

For example 3.4 can be estimated to 3 in whole number.

When adding and subtracting decimals, estimation makes it easier. Operations can be done offhead without counting or using objects. Estimation is very helpful especially with middle school students who are actively doing addition and subtraction questions.

An equation can be solve mentally when allowed to estimate. For example,

1) 9.7 - 3.8 = 10 - 4

= 6.

2) 39.93 + 60.09 = 40 + 60

= 100.

step-by-step explanation:

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
