Primary 4 Mathematics

Introduction:

Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions. In mathematics, fourth graders are usually taught how to add and subtract common fractions and decimals. Long division is also generally introduced here, and addition, subtraction, and multiplication of whole numbers is extended to larger numbers. (Source: Wikipedia)

Example problems for primary 4 mathematics :


Primary 4 mathematics – Addition problem:

There are 190 passengers in trains A and 168 passengers in trains B. How many passengers are there altogether in the two trains?

Solution:

Passengers in car A = 190

Passengers in car B = 168

Passengers in car A + Passengers in car B

So, 190 + 168 = 358

There are 358 passengers altogether in the two taxis.

Primary 4 mathematics – Subtraction problem:

A fruit whole seller had 159 pomegranates. He sold 87 strawberries. How many pomegranate did he have left?

Solution:

The total amount of pomegranate = 159 pomegranates.

Sold pomegranate = 87

Remaining pomegranates =?

So, 159 – 87 = 72

He had 72 pomegranates left.

Primary 4 mathematics - Multiplication problem:

There are 52 sapotas in each bag. How many are there in 12 bags?

Solution:

So, 52 × 12 = 624

There are 624 pomegranates in 12 bags.

Primary 4 mathematics - Division problem:

Joseph bought a sack of 189 kg of flour. He has packed the flour equally into the 3 boxes. How many kilograms of flour were there in each boxes?

Solution:

189 ÷ 3 = 63

There were 63 kg of flour in each boxes.

I have recently faced lot of problem while learning how to solve math word problems step by step, But thank to online resources of math which helped me to learn myself easily on net.
