Answer:

Solving exercise 3 page 148 Math 3 textbook

Problem:

Mental calculation

a) 8000 - 3000 = 5000 b) 3000 x 2 = 6000

6000 + 3000 = 9000 7600 - 300 = 7300

7000 + 500 = 7500 200 + 8000 : 2 = 4200

9000 + 900 + 90 = 9990 300 + 4000 x 2 = 8300

Answer:

Students mentally calculate and record the results as follows:

a) 8000 - 3000 = 5000 b) 3000 x 2 = 6000

6000 + 3000 = 9000 7600 - 300 = 7300

7000 + 500 = 7500 200 + 8000 : 2 = 4200

9000 + 900 + 90 = 9990 300 + 4000 x 2 = 8300

Problem:

a) Find the largest number with five digits b) Find the smallest number with five digits.

a) Find the largest number with five digits

b) Find the smallest number with five digits.

Answer:

a) The largest number with five digits is 99999

b) The smallest number with five digits is 10000.
