Unit 47

Tambah Wang

Tulis titik perpuluhan pada lajur yang sama. Tulis 80 sen sebagai RM0.80 dan RM30 sebagai RM30.00 supaya titiknya sejajar.

Langkah 1

Susun titik selajur

Tulis titik perpuluhan pada lajur yang sama. Tulis 80 sen sebagai RM0.80 dan RM30 sebagai RM30.00 supaya titiknya sejajar.

Susun titik selajur = 小数点对齐
用直式加钱时，两个数的小数点要上下对齐，令吉对令吉，仙对仙。RM24.30 + RM15.45 要先这样排好再算。例子：RM31.20 + RM12.65，对齐后得 RM43.85。注意：小数点没对齐，仙的数字就会加到令吉的位置上。

Susun titik selajur = line up the points
When adding money in columns, put the decimal points directly under each other so ringgit line up with ringgit and sen with sen. Set out RM24.30 + RM15.45 this way before adding. Example: RM31.20 + RM12.65 lined up gives RM43.85. Watch out: if the points are not lined up, sen digits end up in the ringgit columns.

Langkah 2

Tambah sen dahulu

Tambah nilai sen, kumpul semula 100 sen sebagai RM1 jika perlu, kemudian tambah ringgit.

100 sen = RM1

Tambah sen dahulu = 先加仙
先把仙相加，满100仙就换成 RM1 进到令吉，然后再加令吉，这和加法进位一样。例子：RM2.70 + RM1.50，先算 70 sen + 50 sen = 120 sen，换成 RM1.20；令吉 2 + 1 = 3，合起来是 RM4.20。注意：仙满100就要进位，别写成 RM3.120。

Tambah sen dahulu = add sen first
Add the sen first. If they reach 100 sen, regroup them as RM1 and carry it to the ringgit, then add the ringgit. Example: RM2.70 + RM1.50: 70 sen + 50 sen = 120 sen, which is RM1.20; the ringgit give 2 + 1 = 3, so the total is RM4.20. Watch out: 120 sen must be regrouped, so never write an answer like RM3.120.

Langkah 3

Semak jumlah

Untuk tiga nilai wang, susun ketiga-tiganya dalam bentuk lazim, contohnya RM9.90 + RM24.80 + RM15.20 = RM49.90. Pastikan jumlah tidak melebihi RM100.

anggar → kira → semak

Semak jumlah = 检查总数
计算前先估一估：把钱四舍五入到最近的令吉再相加。算完后看实际答案和估计是否接近，也要确认总数不超过 RM100。例子：RM19.80 + RM30.10 约等于 RM20 + RM30 = RM50，实际答案 RM49.90，很接近。注意：答案和估计差很多，就要回头检查进位。

Semak jumlah = check the total
Estimate before you calculate: round each amount to the nearest ringgit and add. After working it out, see whether your answer is close to the estimate, and make sure the total stays within RM100. Example: RM19.80 + RM30.10 is about RM20 + RM30 = RM50; the exact answer RM49.90 is close. Watch out: a big gap from the estimate signals a carrying mistake.

RM24.30 + RM15.40 = __

Tambah wang = 钱的加法
题目要算 RM24.30 加 RM15.40。把小数点对齐，先加仙，再加令吉。最后用估计检查，答案应该接近 RM24 加 RM15。例子：RM12.20 + RM16.50 = RM28.70。注意：30 sen 加 40 sen 不满100，不需要进位，别多加 RM1。

Tambah wang = adding money
You need RM24.30 plus RM15.40. Line up the decimal points, add the sen, then add the ringgit. Check with an estimate: the answer should be close to RM24 plus RM15. Example: RM12.20 + RM16.50 = RM28.70. Watch out: 30 sen and 40 sen together do not reach 100 sen, so there is no extra RM1 to carry into the ringgit.

RM18 + RM27 = __

RM18 + RM27 = 令吉加法
题目是两个整令吉相加。先加个位：8 + 7 = 15，写5进1；再加十位：1 + 2 + 1 = 4。可以用估计检查，答案接近 RM20 加 RM30。例子：RM26 + RM38 = RM64。注意：个位满十要进位，忘了进位答案会少 RM10。

RM18 + RM27 = adding ringgit
This adds two whole ringgit amounts. Add the ones first: 8 + 7 = 15, so write 5 and carry 1. Then add the tens: 1 + 2 + 1 = 4. Check with an estimate of about RM20 plus RM30. Example: RM26 + RM38 = RM64. Watch out: when the ones make ten or more you must carry, or the answer comes out RM10 too small.
