Question

Tamara needs to find 455-364. Her work is below. Explain what is incorrect and find the correct answer.

455-300=155
155-50=105
105-4=101

Answer 1

if you add all the numbers on the right (300+50+4) it doesn't equal 364. It equals 354 rather than 364

Answer 2

She needs to find 455-364 but she only subtracted 354 in her shown work. 300, 50, 4 added all up is 354 only.
